I am trying to perform a simple free-free modal analysis on a single CPS4 element. Here’s the input file:
*Node 1, -50, -50 2, -50, 50 3, 50, 50 4, 50, -50 *Element, Type=CPS4, Elset=Eall 1, 2, 1, 4, 3 *Material, Name=Material-1 *Density 8E-09 *Elastic 210000, 0.3 *Solid section, Elset=Eall, Material=Material-1 1 *Step, Perturbation *Frequency 12 *Node file U *End step
It says that the job was finished but there are no results for all frequencies and some errors appear during the calculation:
It works in Abaqus so the input file must be correct. Do you know what can be wrong here ? Is that a bug or limitation of CalculiX ?
