ERROR MESSAGE IN ALE MODEL

[SREEKUMAR PUNNAPPILLY]

I am encountering the following error message in ALE Model for simulation of blast loading. The structural material is concrete and the material model to be considered is MAT_RHT - MAT_272. 

*** Error 20385 (STR+385)

     The part with ID 1, material ID 1, has a material type 272

     that is invalid for ale solid elements

How to solve this issue?

Regards,

MAT_272 is not available for the ALE solver.

The User Manual Volume II, page 2-1 (MAT), lists all the material models followed by a series of numbers indicating which solvers are appropriate.

                                *MAT_272: *MAT_RHT [0,5]

In this case 0=solid elements and 5=SPH particles.

 

You will need to select a different model for the ALE concrete in your model.                 --len
