Material stress is failed to be tracked

[jiangtao.le]

Hi,

I am the beginner of Opensees based STKO.

I am trying to practice the soil-pile interaction modeling in the advanced e learning courses (https://asdea.eu/software/advanced-e-le ... urses/#022) using the documents provided by Dr.Massimo.

I found that although material.stress was set to be recorded in the SKTO pre-process, the stress is failed to be shown by the post processor. I cannot find it in surface color map or fiber color map (opensees 3.7.0). I use another compter to test with different Opensees version (3.4.0). The same thing happened.

I am wondering if it is because the incompatible issue between the old version documents and the new version of STKO/opensses? I atttach .scd file and corresponding mcpo file for you to check

Best regards,

It's because some elements in OpenSees (those with only 1 gauss point, like the SSPBrick you are using) do not follow the rules and do not accept the material keyword before a gauss point result (like material.strain or material.stress).

For these few element, you need to use custom element results, like strain and stress, omitting the material. in front of them
