Nastran to Code_Aster : elasto-plastic deformation

This time we will have a look at nonlinear material properties, in particular elasto-plastic behaviour laws. This case is taken from a publicy available example on the internet, but the original source is probably this one, for all due credit. To read this article one will need some knowledge both in Nastran and in Code_Aster. The translation between Nastran … Continue reading Nastran to Code_Aster : elasto-plastic deformation

Install Salome and Code_Aster on Windows

On Linux, the official manner to begin with Code_Aster is to download Salome-Meca from the dedicated Salome-Meca web page on the official Code_Aster website, extract the downloaded archive, and then execute the .run self executable that will install a full functional Salome-Meca on your computer 🙂 Unfortunately, Salome-Meca is only available for Linux. This post … Continue reading Install Salome and Code_Aster on Windows

Nastran to Code_Aster: nonlinear gap elements

Code_Aster can really replace in many cases traditional solvers, let's try with a simple problem. This problem will look into a specific contact type, called CGAP in Nastran™ and unilateral contact ("LIAISON_UNIL") in Code_Aster. This case is taken from a publicy available example on the internet, but the original source is probably this one, for all due credit. … Continue reading Nastran to Code_Aster: nonlinear gap elements
