I'm trying to simulate a test model (a simple structure with solid elements modelled in LS Dyna PrePost) under earthquake loads. I have given proper boundary conditions to it(Model consists of a structure made up of beams columns(square X-section of concrete material RHT) resting on soil part(mat_soil_concrete) surrounded by soil PML(Perfectly matched layer)part(meant for mat_elastic_PML)).The structure is already under gravity load and earthquake ground motion curves have been assigned properly. Contact interfaces have also been created in the keyword and assigned properly.

When I run the transient analysis, the solver shows error which is being highlighted in the figure below.

Can someone tell what did I miss?

Thanks in advance.
