    Too large Patran db file

    Hello all, I am working with a big Patran model of around 160MB. The problem is that the more I work with it, sending different load cases to analyze or modifying it, the bigger it gets. I cannot understand why because the model is always the same, I haven't increased the number of elements so...

    Very different displacements in Linear and Non-Linear Analysis

    Hi all, I am using the Marc solution (SOL 600) for solving a contact between two cylindrical pieces (one inside the other) but I've obtained a very different result in "Rotational Displacements" that when I used the Linear Solver (without contact). I tried to deactivate contact zones and ease...

    Problem with non-linear bush

    Hello all I was looking for a way to modelize a displacement limiter and I think I can do it through a non-linear bush. There are two parts in my model, one fixed and another one turning around its axis. My idea is to fit a bush element between these two parts and set its stiffness variable...

    Different thickness field for each shell side

    Hello all, I am looking for a way to define two different scalar fields for the same shell element. The geometry I want to represent is like a cylinder with a longitudinal hole, and I want to discretize it with shell elements. My idea is to define a different thickness function for each side of...

    "Zero thickness" error in SOL 600

    Hello all, I am doing a SOL 600 analysis but Nastran gives me an error of "zero thickness" in some elements. Obviously, I checked those elements and they have properly defined their properties so I don't know what can I do. I've done a lot of linear analysis to that model and all of them have...
