I'm using a linear Eigenvalue Buckling analysis to create imperfect geometry for a Nonlinear Static Structural analysis by using UPGEOM to use a fraction of mode shape 1 and these are working as expected. Here is a video of that model: https://youtu.be/Iqqu92KL5Ko   An Explicit Dynamics (H) model using perfect geometry also works as expected.  

Now I want to use the same imperfect geometry in Explicit Dynamics (F) but the solver issues an error message.

The Tree Filter is disabled. I can't see any imported boundary conditions.

I created the Fixed Support and Displacement in Explicit Dynamics after the import.

Is there another way to import the imperfect mesh into Explicit Dynamics?  I am using Ansys Student 2025 R2.

I also used LS-DYNA (G) where I saw the Imported Boundary Conditions which I suppressed and created the same ones as Explicit Dynamics however I have not yet installed LS-DYNA to run the solver. I noticed that LS-DYNA Student is at 2025 R1.  Do I need to use Ansys Student 2025 R1 to create the cbd file from the Eigenvalue Buckling analysis or can I import the R2 cbd file into 2025 R1 to run the LS-DYNA solver?

Dear Friend

 

I would suggest to use LS-Dyna (2025 R1 is fine - in the back R14 is used always for both 2025R1 and R2).

 

In WB you can just drag and drop the Solution Cell of the eigenv. buckling to the Model cell of the LS-Dyna system and it will be done.

 

Anything let me know.
