Afrer the topology optimization is completed it doesnt find the file? It suggests to combine results but that diesnt work either. What should I do?

If executing in recent versions, replace : ax = fig.gca(projection='3d') by : ax = fig.add_subplot(111, projection='3d').

Thanks for this quick tutorial. These are the sort of tutorials Altair need to have on their learning platform. Back to basics classic text book analysis.

AI will impact FEA

looking for more inspire simulation tutorials. so far everything is so great and also few simsolid examples

For anybody wondering - I found the bug the next morning. Turns out i had the node id in the element.id variable (which is just a really really bad thing). It happened only for Hex elements as it has more than one line and i had the first cell of the line being the id - so for hex elements it took the node id from the 2nd line.

(Are u developing in structural Analysis in finite element analysis) through python right!..

Defeaturing sometimes convert solid to shell or If sometimes I dont have solid but shell. i use volume tetramesh, supress many edges that are problematic then create 2d tria/quad mesh on the faces first and then volume mesh. To avoid tet collapse or some errors . This way I can control the surface mesh.

I really love this series.Thanks Manuel for doing this.

In the 156k model every slave node is disconnected, right because there are new nodes created in between. So the number of groups paths are like 2x slave nodes or something...

This is a very nice video idea. Enjoyed watching!!

Hi Manuel, if you need a topic to cover. Can you cover about the stress linearization and by default how the stress are calculated for top and bottom section points for a shell and then how does one extract membrane stresses?

Thank you for the stream. It is challenging to write a script in real-time. I am an engineer at Raytheon/Collins, but I also have a PhD (my thesis was about optimizing composites using genetic algorithms). As Ph.D. people, we always try to learn something new, right :) For me, it was tcl/tk in HyperMesh. It is LVL80 skill :) Only a few KZbinrs post examples of hypermesh coding: you, plus 3-4 other guys (from India and Vietnam). Of course, recently, Altair guys started to post interesting stuff on KZbin and Altair Exchange. Sometimes, we can read interesting posts in the Altair Forum. Thank you for your work. Yes, it is time-consuming and impossible to monetize it at all, but it is a great input to the development of aerospace and aviation and, eventually, human civilization. Keep producing great videos!

That bug was funny. The stream made me learn new things and was easy to follow.🎉

Hi I want to improve the mid lines algorithm. I tried to make one tcl script but it going more critical for automation.

Hallo Herr Ramsaier, erstmal vielen Dank für ein tolles Video. Wenn ich richtig verstanden habe, gibts zwei Optionen mit wem man XFEM analysis machen kann, entweder Traction-separation cohesive behavior oder VCCT. Aber anhand der Abaqus Doku, VCCT kann keine Rissinitiierung von einer Oberfläche modellieren, die nicht bereits gerissen ist, daher muss ein Clearance zwischen zwei Oberflächen als Riss definiert werden. Können Sie vllt darüber einmal gehen und erläutern? VG

Hi...im not able to put radius to a circle...it shows me in mm...how do i get the dimensions in radius or diameter for the circle???

Thanks. The notebook I got was all wrong. Gave me wrong plot.

Does this run locally on your pc or does it run in their servers? What are the specs of your pc?

Hey, there is also a way to visualize the reaction forces in the GUI of Inspire for the optistruct solver. You just need need to move the reaction slightly, like a remote load, you can do this in Inspire where after you have defined the support it gives a triad. After doing this you can click on the reaction force call out like you would for bolts or fasteners. If you are curious about this let me know, I can shoot you an image. I have gotten this question on support tickets a good bit. Thanks!

This is gold, thank you very much

<3

Would you explain what is different between Altair hyperworks and Altair inspire..

Thank you very much for this channel, by training I am a mechanical engineer working in the mining and mineral processing industry in South Africa. I have developed a great love for programming as well as thermodynamics and fluids after I worked on a project where the bearings on a ball mill were running hot and leading to failure. Having checked numerous drawings and machining tolerances we could not resolve the issue until the bearings were changed. No fault was detected in the manufacturing of those bearings though. I have thus decided to study in greater detail these two disciplines of fluids and heat transfer.

very helpful advice, thank you very much ! it now sounds obvious but it never came to my mind how such little load changes may require more tweaks to cover a wider use of cases.

hmm.. RMS is a time duration of that particular g , so g * time

Can you help me with a script to find list of node numbers in a model?

Mich würde interessieren, wie bist du fachlich zurechtgekommen. Also warst du als Hochschulabsolvent in der Lage sofort die Forschugn in Angriff zu nehmen oder musstest du nochmal einige Grundlagen aufholen ?

Is there any solution for this problem than choosing non colinear indepedent nodes. My Indeoendent nodes are in X direction colinear. I tried giving dependent DOF 123 only. Still it showed the same error.

sir do you give private lessons ?

How come you're able to edit the properties of e.g. the curve you first created? Whenever I try to follow a tutorial that opens with the import of a .fem-file, all solver cards for properties, materials, as well as all additional 'things' I create in the model browser appear as 'ungrouped and are not editable. I cant seem to find a solution for this. I'm using HyperMesh 2023.1 with OptiStruct for the record

Thanks very much. That so usefull

Not related but: Can anyone help me what is wrong with this script? Tried to import it in Hyperworks, won't work. Heheh # Procedure to calculate the average element size proc calculateElementSize {} { set minSize [expr {1.0e20}] set maxSize [expr {-1.0e20}] set totalSize 0.0 set numElements 0 # Get all nodes in the model set allNodes [ hm_getmark nodes 1 ] # Loop through all nodes foreach node $allNodes { # Get connected elements for each node set connectedElements [ hm_getentityvalue nodes $node connectedelements ] # Loop through connected elements foreach element $connectedElements { # Get characteristic length of the element set size [ hm_getentityvalue elems $element characteristiclength ] # Update total size and number of elements set totalSize [ expr {$totalSize + $size} ] incr numElements # Update minimum and maximum sizes if {$size < $minSize} { set minSize $size } if {$size > $maxSize} { set maxSize $size } } } # Calculate average size set averageSize [ expr {$totalSize / $numElements} ] # Display results puts "Average Element Size: $averageSize" puts "Minimum Element Size: $minSize" puts "Maximum Element Size: $maxSize" } # Execute the procedure to calculate element size calculateElementSize

Hi I am sorry for out of topic Did you know why the Hypermesh is so heavy application I have Hypermesh 2023 suite in my PC (Ryzen 5600X, 16Gb RAM, RTX 3060 12Gb). My computer lagging so much even if only I import geometry The geometry is a simple small 1Part (motorcycle shock absorber head) Actually there is nothing suspicious in the Windows Task manager (CPU 10~20%, RAM 50%) I don't know why this can possibly happen Is there anything that I can do to make the application lighter?

Is there a script to find the average element size of your model in Hyperworks?

I don't understand the point of 'b'

intresting short video👍👍👍. may i ask what is the software that you are using?

Is only free for one year?

Muss man für eine Promotion eine gewisse Begabung mitbringen oder reicht Interesse am Fach und gutes Durchhaltevermögen aus? Ich merke in meinem Bachelor Informatik Studium jeden Tag, dass ich hier nicht der Schlauste bin. Ich habe hier auch nicht die besten Noten. Trotzdem könnte ich mir vorstellen später mal zu promovieren.

is there a compilation of scripts or tpls that I can find? like even the simple one like naming and such?
