Hello

For my studies I am trying to model a compression masonry prism. The bricks are modeled utilizing the solid65 element, as they are made out of concrete. However, I wanted to clarify some details that have caused me some doubts during my work.

Firstly, when setting the element, I used the CONCR option of the TB command for setting the material of the element. For CONCR, I have utilized the TBOPT of 0, meaning: general concrete options for SOLID65. If I understand correctly, this means that the following data is the one utilized for setting some of the concrete behavior.

SOLID65 is an archived (no longer actively developed) feature so it's capabilities may be somewhat out of date. Documentation for SOLID65 is in the Feature Archive Manual.nFailure of a concrete element can occur due to either cracking or crushing. If too large a portion of the model has failed to satisfy equilibrium or possibly to make convergence possible then typically the solution will just stop with an unconverged solution. A solution strategy is to use many very small time steps and ncnv,0.nThere is no material model that can be specified for solid65 that includes degradation. If progressive damage needs to be included it is recommended to use solid185 with the microplane material model.nThe meaning of the PLCRACK plot is included with the PLCRACK command in the Feature Archive as indicated below:nn

Dear thank you very much for your answer, it helps me a lot in defining the approach I will take with my model. Best regardsn
