  Hi, which features of Mystran you would need it? As far as I know most of them are covered by CCX or Mecway solver.

  Sergio, it is true - the Mystran's features are covered by Mecway. But an integration with Mystran could allow Mecway to read a dat file and also post f06 or op2 files. I think these are important interfaces and could make Mecway even more desirable - an extra fee could be perfectly acceptable, personally I would consider pay a little more for this feature. Anyway, it is only a simple suggestion to be considered by the development team, in order to increase the value of the product. Best regards.

  ffontana, in the last two versions there is a new very powerfull solver available for Mecway, OpenRadioss. Guess that the developer will include some more features of this one before tryng other. By the moment Mecway has the intenal solver, CalculiX and now OpenRadioss. If I remember well there is another solver available, Tochnog, and you can even prepare models for OpenFoam as well with Mecway.

  It would be nice to have elements equivalent to NASTRAN/MYSTRAN CROD and CSHEAR elements in Mecway or CCX. I want to do an aircraft internal loads model and these simple elements make data easier to extract to use in detailed models or hand calculations. These elements are still the standard in the aerospace industry for internal loads. The big advantage is that you add the skin extensional stiffness into the rod area as the shear panel doesn't have extensional stiffness. For a panel under tension all of the skin area is added into the adjacent rod areas. For compression less skin area is added into the adjacent rod elements to adjust for effective skin width.
  
  The rod elements are not a problem because you can just mark them as truss elements. The quad elements are not as easy. I've been making them orthotropic and setting the extensional moduli to very low or zero.
  
  I've also looked into parsing the liml or inp file for conversion to NASTRAN bdf. I have a python file that will read the liml file and fortran 90 source code for a Abaqus to Nastran converter.
