Simcenter 3D, the most powerful finite element modeling software enabling you to predict your product's performance quickly and easily.

I don't remember this command in NX11 in CAD/Modeling. It was available in NX11 in Pre/Post when in the FEM, AFEM or SIM. If it was in Modeling in NX11 it isn't there in the recent releases.

Glad it was helpful!

I would think it would be but trying it doesn't seem to allow editing the subcase name in the spreadsheet. You can get to it by right clicking on the solution and selecting subcase manager. Then right click in the entity list and select edit in spreadsheet. It appears to only allow editing the scale factor or Y or N cells. After editing in the spreadsheet you need to select the Add-Ins ribbon and then select Update Table for it to pass the spreadsheet edits back to Simcenter 3D.

The yellow warning sign means that there are conflicting constraints and Simcenter 3D will resolve the conflict at solve time so not action is really needed. To avoid conflicting constraints, as a best practice you could split the face in the idealize part so there are two edges instead of one. Then you can apply the constraint to the edge you want. If there is a CAD change the finite element model will update and the constraint will remain associated. As an alternative, you could expand the "Excluded" block in the constraint dialog then select the nodes you don't want to include in the constraint. I don't recommend this since selecting nodes instead of geometry will not survive a CAD change and finite element model update.

The Enforced Displacement Constraint - Translational Components - Field only uses DOF1-3. If you have DOF1-6 you can truncate the field by first exporting it to a CSV file. Select the rotational DOF4-6 columns and save the csv file. Then when creating the EDC-TC-F, don't select Existing Field From List as shown in the video at time index 7:37, select table constructor, Independent Domain - Cartesian, Next, Delaunay - Fast, Next, Import From Text File and select the csv.

I'm glad you liked it. 1. It is the same process independent of what solver environment you have selected in Simcenter 3D 2. The same process could apply for a non-linear multiphysics solution, however, if you have multiple time steps you may want to create a table of fields or use our multiphysics environment. 3. I have a few videos on mapping temperatures. kzbin.info/www/bejne/nXfMYqN7fr-Drs0si=LzOkNhER4zYC9P1w As a best practice apply load and constraints to geometry so they can survive a CAD change and FE update. Don't use groups. Use selection recipes instead. kzbin.info/aero/PLRhczELP7wYLNDPG_lie1N85MUJsAJGD_&si=k0jc_tGne8KouKLf 4. You can apply material properties to solid bodies or to the mesh collector. If the designer has specified a material property in the CAD model, it removes a potential source of error for the analyst to simply inherit the material properties in the mesh collector.

I'm glad you like the videos. I have a playlist on brick meshing here: kzbin.info/aero/PLRhczELP7wYK_x_XSOOuE9ljXF5Ig_ghM&si=rdMSMHD0ykiTfA1m Also, there are two videos in particular that may be helpful: kzbin.info/www/bejne/i3iadGqemLWqja8si=pwix6bf3LVZXRwsQ and kzbin.info/www/bejne/f4ayipZ4gt-KqrMsi=VSB4lqz220cGVXiX

@@Simcenter3DTipsandTricks Thank you for getting back to me. I appreciate the effort put into the blisk meshing video; however, I noticed that it does not reflect the updated graphical user interface (GUI). While the 2:45-minute video offers some useful insights, it tends to cover relatively straightforward concepts. To enhance the learning experience, I believe it would be beneficial to incorporate a more complex 3D model, ideally showcasing a full 360-degree view. This model could demonstrate a range of advanced features, such as extruding shapes, creating sketches, and splitting bodies. By using a more intricate model, you could illustrate how these features can be effectively utilized for brick meshing. Additionally, it would be particularly helpful to include a segment that focuses on the process of extruding or separating bosses from the main body. This aspect is crucial for achieving optimal brick meshing and would provide a practical example that many users would find valuable. I believe these improvements would make the content more engaging and informative for users looking to deepen their understanding of brick meshing techniques.

@@SamSammy-n7p Great suggestions. I'll keep them in mind for future brick meshing demonstrations. Have you seen the one on hex dominant meshing? kzbin.info/www/bejne/aKWvZXpvfNihpcUsi=4wIe50jO9UkCXo7l

Sounds like you may want to run a transient event in response dynamics. Start by creating a time pulse signal with the function toolkit. In the Pulse Function Creation dialog, select Sine, Full Cycle, amplitude 3, time period 1/66 (not 1/33), number of cycles 33, number of intervals 330, ordinate type acceleration, unit type g. Then select a record name 3gat33hz then browse or create an afu file to put it in. Be careful when creating the signal as the period is not 1/frequency as you would expect. I plan to write up a support case to get this corrected. Then create a new transient event. Create a new excitation using the 3gat33hz function created above.

@@Simcenter3DTipsandTricks Thanks for your advice

You can do that in response dynamics as shown in the video here: kzbin.info/www/bejne/nIaQdmSdp7KHgKssi=9fc5FjnQN9eqmCOZ&t=2805 You can see the effective mass at the bottom of the screen.

@@Simcenter3DTipsandTricks thank you for your answer. But in this video that you send me model have constraints. I don’t. I’m trying to perform for a free-free model.

@@furkankycak6462 Modal effective mass is independent of constraints. You could still not apply any constraints and enforce all DOFs for your enforced motion location.

Glad you are enjoying the videos. Did you apply the load in the first (nonlinear statics) subcase also in the second (modal) subcase as well?

Definitely easier with Teamcenter. If all the files are in the same folder you could copy the folder. Just make sure your assembly load options are set to load from folder.

Instead of using mesh mating conditions for connecting the discretized weld to the parts being welded you would need to use surface-surface glue instead. Then you could control what glue is used when by creating simulation object containers in the transient subcases but this is not possible in a nonlinear transient coupled thermal structural analysis, however, it is possible to create simulation object containers in the subcases of a nonlinear transient structural analysis. You could solve the thermal transient analysis separately then apply the resultant temperatures as a table of fields temperature load to the nonlinear transient structural analysis with simulation object containers that control what glue is applied when. I haven't tried it this way to see if it makes much of a difference. If you try it, please let us know if it makes much of a difference in the results.

Hi, you will need to specify a liquid surface vector. Mine was already correct in the video so I didn't go into the pulldown to the right to specify a liquid surface vector. Select the pulldown to the right of Specify Vector and you will get the full vector specification dialog where you can use a number of methods to define the liquid surface normal.

​@@Simcenter3DTipsandTricks thanks for your soon answer. Yes, I already did it. I have put a liquid surface, considering the vector but the results are not similar to the rotated hull. Even over the inclined vector the hydrostatic pressure is applied but that is a mistake because the load distribution should be under the inclined liquid surface. That is the problem that I have now. By the way, after to set the liquid surface vector, I put the specify point in the maximum level of the water.

There are many ways this can be done. I show a few others here: kzbin.info/www/bejne/d4aQXqmoa9Nnr5osi=_F4KidT5UPSv7N68

Glad you liked it. I put the loads and constraints in the global containers which applies them to all subcases. The point of the subcases in this multistep nonlinear analysis with sequential dependence is to first spin up the structure to preload it then find the modes while the structure is spinning.

I'm glad you are enjoying the channel. It is not possible to simulate a hinge in SOL 101. A hinge by definition is a large displacement analysis and will require a nonlinear solution.

The FOS was only looking at the hub, not the OD teeth and ID spline. After adding the teeth and spline you could analyze again with loads and constraints on the teeth and spline with either Performance Predictor or Simcenter 3D. Not sure about the hardware requirements for GPUs. I have an NVIDIA Quadro RTX 3000.

Yes, I created this for a Creo customer, however, in their test case only the material name was imported. It should support properties as well since the fields are standard in the STEP 242 file for quantities like Youngs modulus, Poisons ratio, density, etc. Check the export settings and ensure the user attributes are being written out to the stp file.

Solid elements have only 3 (translational) degrees of freedom where shell elements have all 6 (translational and rotational). If the connection is along a line between the shells and the solids, it will act like a hinge. Instead of using 1d elements to make the connection, consider using edge to surface glue (in the sim - simulation objects). Edge to surface glue will create imaginary springs out to the width of the shell elements and prevent hinging. Another great place to ask these types of questions is on our community forum community.sw.siemens.com/s/ under Simcenter 3D.
