In this post we will have a look at a slideline contact problem, including friction. 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 and … Continue reading Nastran to Code_Aster: slideline contact

In this post we will have a look at a modal frequency response analysis. We will find the frequency response of the structure under a pressure load and a nodal force with a phase lag. A modal damping is also applied. This case is taken from a publicy available example on the internet, but the original … Continue reading Nastran to Code_Aster: modal frequency response

In this post we will have a look at a simple linear modal analysis. 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 and Code_Aster … Continue reading Nastran to Code_Aster : normal modes

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

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
