FEA
Version 19.0
Mecway 19.0 is now available at the link below. As usual, it's a free update for all existing license holders.

Spanish language manual thanks as always to Germán Bresciano and now included in the Help menu.
Changes:
General
Geometry preview is faster and doesn’t stop to ask for a 2 minute timeout.
Compression only support for the CCX solver.
Forced convection for CCX. Includes fluid network elements, mass flow rate constraint, and forced convection load.
Temperature conflict check for time dependent temperatures in mechanical analysis with CCX.
Time dependent temperatures in thermal transient analysis with CCX.
Show model edges works for geometry view of STEP files.
Button to open working directory from the CCX solver window.
Strain energy density output for modal vibration with CCX and static and modal vibration with isotropic solid elements and the internal solver.
Frictionless support on the 2D faces of shells no longer constrains rotational DOFs.
Updated MKL version for internal solver. Fixes abrupt crash during Matrix solving stage on some workstations.
Change element shape converts between linear and quadratic elements in one operation.
Select elements by shape. Part of Select elements by… which replaces Select elements by number.
Imaginary component of displacement for cyclic symmetry with CCX.
Bigger hitbox for mouse picking line elements.
Poisson’s ratio available as a variable in solution formulas.
Laminates can be used in the same model as all other mechanical element types and elastic support.
CCX thermal transient no longer allows temperature constraints that conflict with initial conditions.
Tutorials updated and merged into a single manual.
CCX solver window appears if there are any warnings from generating the .inp file.
Export matrices and load vector have a note saying that units are m, kg, s, K.
Deformation scale factor shows the constant magnitude while animating instead of the instantaneous scale factor.
Error message if OD is less than ID for circular tube.
Removed
Quad dominant, Quadratic elements, and Fit midside nodes to geometry cannot be turned off in Automesh 2D or Automesh 3D.
“Always show configuration tabs” option.
Some menu options from timeline graph (Copy image, Save As, Print).
Error message about material types being compatible with the solution field variable.
Bug fixes
Contour plot values slightly outside the specified range were being colored as inside the range. This error is reduced but still present.
Bug 36 for frictionless support and shows a warning when solving for node rotation.
Bug 37 frictionless support on shell/beam and solid common nodes.
"*ERROR reading *NODE/EL/CONTACT FILE SECTION FORCES And OUTPUT = 3D are mutually exclusive" with section forces and nonlinaer quasi-static.
No longer exports unused materials to .inp files which can unintentionally trigger a nonlinear solve.
CCX truss connected to beam disconnected in the Z axis in some cases.
Other minor bugs.

Congratulations on the new release.
I'm especially excited for the compression only support being usable CCX as it makes sense to be used for pinned boundary connections when the stresses near the pinned hole aren't completely irrelevant.
Also, you're not kidding about geometry loading faster! I had a model with a lot of surfaces (Topology optimized by external consultant) that wouldn't load in Mecway in any reasonable amount of time and now it does in seconds and even meshes without any major problems!
Thermo-mechanical coupling will be very useful to me.
Still need to do more tests but thermal effects combined with only compression and plasticity will be a powerful feature.
