    Hi everyone, I think I have a problem with a facade model. Behind the facade there are three beams: the one at the bottom is fixed, the other two are free. I applied a displacement to these two beams. As a result, I conducted a time-history analysis. In practice, I applied time histories to the...

    Shell 2D

    Hi everyone!! Can anyone control the displacement that i calculate for a shell 4m x 4m x 0.1m? I consider them fixed at one edge and subject at the two opposite corner a force of 1000 N in the x direction. I divided the shell into 4 isoparametric elements. I share the mathematica file. All...

    abaqus isoparametric elements

    Hi everyone, i have a problem with the stiffness matrix generated by Abaqus! I have do a simple example: a plate in 2D dimension, subject to horizontal forces in the plane and stuck at one end. I resolved this problem in Wolfram Mathematica using isoparametric elements 4-node and i calculate the...
