I tried performing non-linear analysis of a RCC column in ANSYS 2020 R2 using SOLID65 and CEINTF. I got the following errors. I have attached the SOLID65 and CEINTF codes and the excel sheet containing the TPBT command. I have also attached the literature publication which contains the model that I want to analyse in ANSYS 2020 R2. I am just a student who is learning ANSYS and I tried to perform the above mentioned analysis with reference to the video named "ANSYS Tutorial: Nonlinear analysis of Reinforced Concrete Columns and compare with test results" uploaded by "Thanapon Buamongkol" in YouTube.
