Version 12.0 is now available here
https://mecway.com/download/mecway120rc.msihttps://mecway.com/downloadIt may be updated soon if problems are found. The final one will be on the download page.
Changes:
GeneralSurface refinement for STEP files.
Selecting a constraint equation in the outline tree also selects its nodes.
Formulas in the solution can include density, Young’s modulus and specific heat (not temperature dependent).
New element tool allows you to choose the component.
Invert selection tool won’t select shell edges or beam ends so it’s convenient for swapping to the opposite faces of a shell mesh.
Compatible with Gmsh 4.2.2
Move/copy tool allows formulas.
Automesh 3D with a shell mesh allows either element face to be on the outside and shows non-manifold errors graphically.
Elastic support is more accurate on corners of coarse meshes by using the average normal direction insted of each face's normal.
Bugfix: Change element shape no longer merges adjacent parts except for tri3->quad4 and tet4->hex8 subdivision.
Tresca stress renamed to “maximum shear stress × 2”.
Various bug fixes and minor UI improvements.
CCXNew solver window with convergence graph, loading converged time steps while it’s still solving, and graphical identification of nodes and elements that have errors.
Faster loading solutions.
Beam internal forces (bending moment, torsion moment, shear force, axial force).
Elastic support. Can be used in place of fixed support or frictionless support if those conflict with other constraints, or as a weak spring on unconstrained parts.
Point mass.
Constraint equations.
Cyclic symmetry for nonlinear static.
Comments
Also, the new CCX solver windows looks great but... can you explain a little how to use the new convergence graph? What we should look and how this could help to improve our simulations? In the future, is possible to add a new tab in the same window showing the summary information of the .sta file?
Best Regards
For using it to inform decisions, I saw one case where the number of contact elements appeared to be converging but was so slow that CCX repeatedly gave up at 60 iterations. That was solved by increasing the number of iterations for CCX using *CONTROLS. In other cases, it might be oscillating which could be a sign that contact stiffness is too high. This picture is the PipeClip.liml sample with a very high contact stiffness compared to the normal value.
From what I can tell, the .sta file contains a subset of information in the .cvg file/graph plus increment times so I don't think it's much more useful.

What do you think about a possibility of creating mesh criterions and to assign them for the varius components?
At least could be usefull the possibility of assign the same criterion to all components
There's already slightly smoother material library under Labs -> Import from library. It enables buttons for Assign material from library and Save to library.
Edited... is in the material window!
