For the example part I would leave in the CAD program only one side of the part faces, then in Mecway mesh as surface and extrude along element normal this meshes to create hexas/wedges. Then is a matter of using some glue (ccx TIE or Mecway glue co…

Tahnks! I will check it, but for what I read by the moment... looks very ugly, no interface, to much hand writting cards... only for mesh generation!!! I would like to see some real cases of meshes gerated by them, mesh result and mesh procedure. …

Is there an foamyhexmesh for Windows?????
-
Can you share some simple models to make some tests? Normally for 2D meshes I'm using Gmsh, that gives me more quads (and then hexas by extruding) than Mecway/Netgen. This is about 97-99% of quads, if you need 100% quads then you could use the trial…

Nice! One thing that I notice while running insane big models in CCX is that Mecway itself took a lot of memory also while is being solved. One workaround is to export the model as .inp and then close Mecway and lunch CCX from command line, then w…

Personally I preffer to define the time amplitude table as (with time step 1) *AMPLITUDE,NAME=AMP_1 0,0 1,1 Then the displacement boundary condition would be writted as *BOUNDARY,AMPLITUDE=AMP_1 pipe_end,2,2,-12e-3 So in cas…

Read as: 2,2 are the DOFs, so it means "from DOF 2 to DOF 2" that is only 2 (but you could have 1,3 that is 1,2,3...or 1,6 or 3,5...). DOF 2 is Y displacement 1 means "apply a displacement of 1 multiplied by the amplitud of the step", so as in…

Is a very common file format for write FEA/CFD results, and there is a postprocessor called Paraview freely available that can open this vtk files. You can add a little of candy for the eyes to your results using Paraview. Regards

Multiple material assignment could be a good candidate for liml manual editing.

I found the same error on several models, even solving wit CCX. My solution is suppress the EQUATIONS cards generates by Mecway and use TIE in place that allow both nodes be in different "gluing" relation. What is the difference between using equati…
-
Hi Víctor, i'm very pleased to hear that you will work n VTK support. One thing that I miss using Paraview is the hability to hide and show components, can you take this in mind? Regards
-
Dave, in this case you can use the CCX features directly from the Mecway interface, select first 3d no lineal analysis and then the CCX contact feature will be available as a new boundary condition. Normally you can start with the default setting a…
-
This is the model solved with contacts on CCX, you should play a little with the friction coeficients also. I made a first run without defining the contact between the bolt shaft and holes, and due to the lateral loading the nylon pad slides away fr…
-
Vicotr, I have noted that the cutting plane cuts leaving the complete elements, so it doesn't form a flat surface. Is possible to cut also the elements? Regards
-
You can easily solve it in CCX, contact treatment is really wonderfull in this last versions. You could even model the bolt (or rivet?) preload by means of a thermal load. Regards
-
Great!
-
Another option would be to export the results as vtk. True is that there are two options available (one command line utility and the other is Candy Store) to made it, but they are not very reliable.
-
Some pictures of my first model postprocesed in this way. I really miss the usefull engineering units in Paraview so I must be very carefull. Once you play a little with other postprocesors one can really appreciate the god job done on Mecway to ea…

It will run a set of standard problems and checks against know results, then inform you of any discrepancy. In Windows normally there are very few test with slightly different results, but I have an installation that give me almost all results diffe…
-
Is always good to check if the installation is working ok, on the bConverged start menu there is an icon to run a set of standard automatized tests. A few weeks ago I start to have wrong results, and after a lot of headaches I found that the proble…
-
You catch the idea. Guess that the most important is to avoid the automatic pictures, I have seen several automatic reporting tools and they are really a bad idea, a wast of time and paper. From the list that you have made maybe left boundary condi…
-
Me neither. I have found sometimes in tetra meshes done in another programs that Mecway shows some bad elements were the other program show no errors. Guess that this problem is more frequent with second order elements. Would be nice a feature to m…
-
I was thinking in write some small scripts for automatizing this kind of task from outside the GUI. I work weeks ago in a big assembly with 50-60 components, and adding the same material STEEL for all was a pain (due to the time delay that Mecway to…
-
Great! I was able to select it all using the slice control, but is not very comfortable.
-
Another good feature would be that the first step/igs/stl mesh be the "default component" . Now this default component is always empty for my models unless I manually move the elements (but guess that loosing asociativity).
-
Hi Morten, first... you should ask to Victor for the improvement, I'm just a happy user of Mecway software.... :-) :-) I agree with you, a CTRL and SHIFT selection modes on the tree would be very helpfull. Regards
-
Normally what makes you fails the meshing algorithm is a very small surface or other small error on the model. In order to isolate what I do is in the CAD program is divide the volume in two sub-volumes, with any tool that your cad could have. Then …
-
Also when working with big assemblies would be great to have the possibility of select not only nodes/faces/elements but also components on the graphic window (maybe in meshing mode and also in geometry mode). I need to hide some of them and as they…

We are in the same situation, I had Abaqus an NX Nastran in the past, but now the licences had been cut.

Scott, you should look for Code_Aster, guess that they have explicit implemented (at least have seem several impact test done with him).
