Joint Reaction in Response Spectrum Analysis Using APDL Script

This video explains the how to extract the joint reaction in dynamic analysis in ANSYS workbench using APDL Command script. It also explain how to perform modal analysis and response spectrum analysis using workbench. It briefs various steps to extract the reaction which is not possible using force reaction probe in ANSYS.

Thanks for the useful content sir, can you please tell In random vibration analysis the value of reaction force at joint is what sigma value

[@Bala92635]

Sir it's not working in Static structural analysis, I wanted to verify whether the result given by this Apdl command is equal to joint probe, but Apdl command showing zero forces.

Check analysis setting and make sure nodal forces are ON

Hello, Thank you for your video. I have a remark about this APDL command in spectral analysis. Why the results change when We run the command twice and the values ​​are very large. I tested the command on the 2020R1 and R2 version and it's the same bug. Is this the case for you?

[@graspengineering9249]

It should not happen, it might be happening because of the name syntex at output. You should not repeat the same name like my)fsumFX_X1,...., use different names. Also you should cross check these commands in static analysis, get force & moment reactions by prob and by script, both should match. Then you can use same script in RSA.

Hello, please, can you assist me with the numerical modelling of a timber footbridge?

[@graspengineering9249]

You can let us know what are your difficulties for analysis, we will try to reply.
