Hi, I’m currently studying Fliud-Structure Interaction and using calculix coupled with other fluid solver to solve aeroelasticity problems. I’m new to calculix, so I cannot output my desired results through editting input deck.
Many experiments study flutter with modal analysis, and their results are shown as generalized displacement per mode. To test my program’s accuracy I have to generate something like that from my calculix 2.20
I noticed that in Abaqus we can use *MODAL PRINT in inp file but in calculix it doesn’t work. I am writing for help as a result. Can calculix output anything like that? Thank you!
I have to start Calculix with *Dynamics or Modal Dynamics, since I use preCICE to couple my in-house CFD code and only this two types are supported for transient fsi. So PU cannot be output.
*MODAL PRINT in Abaqus outputs generalized coordinate (modal amplitude and phase) values in modal dynamic analyses. CalculiX doesn’t have any direct equivalent so you would probably have to modify the ccx source code to get such output.
