Hello Everyone,

I’m carrying out an explicit analysis simulating a high-speed compression test with ANSYS student 2022R1.

I use isotropic elasticity together with multilinear isotropic hardening. The analysis is assumed to be axisymmetric since my specimen is cylindrical. The upper edge is given a velocity B.C. of Y= - 4m/s (and free in X), the bottom face is given a displacement B.C. Y=0, X=free, and the left vertice of the bottom edge (the one on the Y axis) is fixed.Could you please advise on the following issues?

1.  It seems that I cannot set a user defined result EPPL, EPEL or EPTO. Each time I try to insert these quantities and solve the model, the following error appears: “An error occurred when the post processor attempted to load a specific result”. Is it something I’m doing wrong?  Are those results unavailable in explicit analyses? If this is the case, what is the reason

      2.  Similarly, I cannot get results for FVECTORS / ENFEVTORS. Are these unavailable in explicit analyses?

     Many thanks,

     Costas

Hi Costas,

 

The requested result items are available with MAPDL solver and not with an Explicit analysis.

Hi Ashish,

many thanks for your answer.

I just found another user defined result available in Explicit Dynamics, which is STRAIN_XX/YY/ZZ. I suppose I can use this to get the total strain. Is that right?

Regards,

Costas

Hi Costas,

The expression looks fine. The same can be seen under the worksheet as well. Also, please check the following forum post:

Many thanks Ashish.

I will mark this thread as answered now.
