Version 6.0 released

Victor

Mecway 6 is available at the link below. It's mostly minor improvements in response to requests. All licences that include version 5 are also valid for version 6. That is everyone who bought it after 2015-11-15. Just re-enter your product key to activate it.

Edge detecting selection tool

Refine x2 does local refinement with all element shapes.

Refine custom has a live preview and is limited to 40 subdivisions per direction.

Quad local refinement x3 is extended to include all line, triangle and quadrilateral element shapes. Renamed to "1D/2D local refinement x3".

Rotate/copy only allows rotation about one axis at a time to reduce ambiguity.

For CAD files, you can easily create a local refinement at a node using "New local refinement" on the node context menu.

Invert selection works in the geometry view.

Components meshed from CAD files are named using the file name for easier identification.

Undo and redo buttons are disabled if they won't work instead of popping up a message.

More undo levels for small models, typically less than 200,000 nodes.

CCX interoperability:

Solver choice (CCX or internal) is now part of analysis settings and saved with the model. This allows the available loads and constraints, materials and error messages to be appropriate for the chosen solver.

64-bit CCX binary and source code are distributed with Mecway.

Automatic time stepping option in Analysis settings.

Mechanical loads and constraints that are specified as constant are no longer ramped when time steps are defined. Define ramping explicitly with a formula or table instead.

Displacement, frictionless support, and node rotation can be time dependent. This is limited to nodes that don't have any other non-zero constraints on them.

Temperature for thermal stress can be time dependent.

Nonlinear dynamic response analysis type added.

TIE option with position tolerance added to Bonded contact.

Initial displacements for dynamic response.

Pyramid elements allowed by exporting them as collapsed hexahedra for mechanical (C3D8, C3D20) and thermal (DC3D8, DC3D20) analysis types.

Saving to the .inp format is now only intended for CCX and has lost some Abaqus compatibility. Particularly with *ORIENTATION and circular beams where the two programs differ.

Enabled orthotropic mechanical material type for solid elements in nonlinear analysis.

For nonlinear analysis with no time steps specified, only the solution at the final time step is displayed.

Node rotation is enabled for Nonlinear static 3D.

Output messages are no longer truncated when they're very long.

Solver panel shows progress by time and iteration number.

Disabled nonlinear materials for linear analysis types.

2D and axisymmetric models automatically enforce zero node Z coordinates which is required by CCX.

Command line solve parameter works.

"Write solution to liml file" and "Write to CSV file after solving" work.

Inverted elements in 2D and axisymmetric analysis types are shown as errors because CCX doesn't allow them.

When writing .inp files, material definitions are moved to be after sets and sections to make hand editing easier.

Internal solver:

Navier-stokes convergence test is more robust.

Navier-stokes solver window shows convergence graph.

Moment load enabled for modal vibration 3D to use for stress stiffening on shells.

Display:

Show origin setting is persistent.

Deformation scale factor is displayed in the graphics area.

Node coordinates in the table have a units option.

Density is moved to a separate tab in the material properties window.

Icons scale smoothly with the DPI setting instead of in increments of 100%.

150% DPI setting causes graphics to scale by 100% instead of 200%.

Renamed "Amplification factor" to "Scale factor" in deformed view settings window.

Other file formats:

Component and face selection names are included as physical entity names with Gmsh export.

Opening .inp files prompts for the unit system of node coordinates. However, other quantities in the file will still be treated as m,kg,s units.

Removed:

Graduated mesh options in Refine custom.

"Quad local refinement x2" and "Hex8 local refinement at a point". They are now included in Refine x2.

Quad9 element shape.

Fluid potential flow 2D and 3D analysis types. Use thermal steady state instead and interpret the meanings of the variables appropriately.

Magnetostatic 2D analysis type.

Templates. Use Refine custom and the enhanced Refine x2 instead.
