Mecway 30 is now available at the link below and includes the Spanish language manual translated by Germán Bresciano.

Only a few changes this time
  • Formulas (without variables) allowed in inputs for most meshing tools, interpolate, and refinements for mesher.
  • Shell offset can be defined in Loads & Constraints → Element offset as well as the existing Shell offset in Element properties.
  • Flexible joint on beam (released DOFs) for Frequency and Dynamic response 3D analysis types with the internal solver.
  • Self contact with a single face selection for unilateral contact with OpenRadioss and CCX.
  • Option to omit generated keyword blocks for OpenRadioss. Called modify starter keyword.
  • Mystran solver installed with Mecway. Imports solution from Mystran. All Nastran options renamed to Mystran.
  • Bug fix for Split step assembly to allow MANIFOLD_SURFACE_SHAPE_REPRESENTATION.
  • Bug fix for OpenRadioss. A blank custom model definition inserted a newline which corrupted the format of the file.
  • Bug fix. Graphics disappeared after reconnecting via remote desktop (RDP).

    Wohoo! :D
    I especially like the self-contact thing because then I can more easily suppress it for debugging than when it is in the custom model definition.

    Thanks! I tried installing Mystran with the 29 version and didn´t work, results were not imported, will try again now. In which cases Mystran would be better than Internal, CCX or OpenRadioss solver? The only thing that came to my mind from my days of using Nastran was the inertial relief option for non constrained models.

    How is that about "Formulas (without variables) allowed in inputs for most meshing tools, interpolate, and refinements for mesher."?
  • VictorVictor
    @German Formulas are for a bit of convenience doing things like this


    @Sergio Mystran isn't really better at anything than the internal solver, unless you prefer Nastran input deck format or manually add some features it has like CBUSH or full control over RBE2/3 parameters. It doesn't yet have inertia relief.

    I like the addition of Mystran as a solver option. I experimented with it in version 29 including the 'Read Mystran F06' Lab option. The initial implementation works well and look forward to more integration. (I haven't installed v30 yet.)

    I'd like to see support for CSHEAR/PSHEAR cards. I want to use them for some aircraft internal loads models. I wrote about it here: https://mecway.com/forum/discussion/comment/8229/#Comment_8229

    I looked at custom bulk data but that only works for small models as there are node numbers on each card and the modify bulk data entry only deletes cards at this time. Also tried ortho properties using shear modulus and very small extensional moduli but that didn't give the same results as shear elements.

    Thanks, Ken
