    Thermoelastic check problem

    Hi everybody, I´m performing a thermoelastic check to a FEM with Patran/Nastran, that is formed just by shells, beams and MPCs. I have followed the rules to perform the analysis as are; same CTE, poisson´s coef. and Elastic modulus, as well as RBE2 with 0 length and no offsets, the structure is...

    displacements in sol103 (normal modes analysis)

    Hello everybody, I have performed a normal modes analysis to my model and I have obtained the first eigenfrecuency at 200Hz, but when I look at the deformation it is very high (20mm). Does anybody knows if it is normal??? because I have seen other analyses and displacements are lower. I don´t...
