hi everyone,
I am doing a simulation of a Prestressed concrete containment vessel for internal pressurization test. currently i have made a 3D concrete model and embedded a reinforcing structure and tendons into it using embedded region option. but during analysis, it is showing that ratio of deformation speed to wave propagation speed exceeded 1 in some elements and the job is getting aborted. someone pls help me figure out what could be the reason. I have attached my input file for reference......thank you....
