Looks like the Pastix build has matured, is available compiled for Windows or one must do the procedure?
-
Would be great to have this instruction (install Pardiso and configure multiprocessor) as a stikie post in the forum (very like the welcome post), lot of people ask for them.
-
Hi, maybe you could do the first point using the CCX solver and Cyclic Symmetry boundary condition (you model one slice and you have the result for the whole pizza), about stacking... that could be done on Paraview translating the CCX results to rme…

Have tried SharkCAD and ViaCAD years ago, they are not better than the Alibre basic package. These days have a project where I need to model tubular frames, did the first one with FreeCAD, and start to try Alibre, but they lack some basic feature as…

I add another, in the Stress Linearization feature, can be the SCL visible when is definied? Now is only visible the nodes, and the line appear when the stress linearization window is closed. Also, when the saved SCL is clicked on the model tree, wi…

That's the exactly procedure, normally you should mold standard samples (cilinders about 32 diam and 18 in heigh if I remember well) with your specific rubber, then you measure on a dinamometer the load deflection curve in compresion. After that you…

I just trying (suffering) FreeCAD also, but you can take a look at Alibre, they have a basic CAD package for about usd 120 that... has less features than FreeCAD but at least a civilizated interface. You can try also Onshape or Fusion360.

There is an option to launch Mecway from command line to solve a problem without opening the GUI. Anyway being able to it directly from the interface would be great, now for big problems take a lot of memory to show it plus to solve it. Look in the …

As everybody says, I'm waiting also an inspired hero that compile this new version.
-
Since I installed Pardiso never back to Spooles!
-
Have someone worked with CFD using CCX?
-
Well, there are a lot of steps to get the mesh 1) Be carefull while modeling, keep radius constant and realistics, better to model as surface and then add the thikness to check that also the mesh could be extruded 2) In CAD add extra face divisions…
-
Hi, just to revive this thread, attached is an example of the secuency of modeling (with OnShape) and meshing (using Salome) with quads and then extruded to get hexas of a bracket made in steel sheet, very similar to the one of @JohnM . It takes a l…

This is a very usefull plastic material database, it has properties and stress/strain curves for lot of comercial polymers, and even at different temperatures. https://www.campusplastics.com/

@tk1537 , if I understood well, following the option 4) what you would get is CCX with out of core capacity. The CCX executable available from CalculiX site works inside of core (put all the stiffnes matrix in RAM only), so if your problem is too b…

Licences :-(

Is there a reason why is not readily available an out of core MKL version of CCX?
-
Is increddible, but I have exactly the opposite experience on your points, I do 90% of my meshes using Netgen, even feel more comfortable with the standalone version of it than Gmsh. And again, I found very usefull Salome, mostly for creating struct…
-
Can you share the geomety? Normally what I do is split the faces in the CAD program available, then export the cad to Salome were I mesh with quads, the extude to create the hexas. Another way would be creating the elements in Mecway directly, but c…
-
For that kind of part I would suggest to use hexa elements, and have at least 2 second order element in thikness.
-
@rwhirley , you can postprocess the results and do the simmetry using Paraview.
-
Congrat, I'm testing mostly the improvements in display performance for big models, and looks very well. One thing, while I was solving a problem, have tried to test the center of mass tool, it open the window but as it doesn't have defined densit…

I have a DELL workstation at work with Xeon and Nvidia Quadro, I don't see the benefits today (in fact since years) compared with standard good hardware, but, it's a enterprise decition. In the past there was huge difference between performance of w…

Have tried with an old Lenovo T420 laptop: SOLVER: CCX Pardiso 2.16 using 4 cores CPU: Intel Core i5 2520M @ 2.50GHz RAM: 8.00GB Doble-Canal DDR3 @ 664MHz HD: Hitachi HTS723225A7A364 Run Time: 9 min 45 seconds (!!!) Looks like the 1:43 mark is ve…

Solver: CCX Pardiso 2.16 using 18 cores CPU: Intel(R) Xeon(R) CPU E5—2697 v4 © 2.306Hz 2.30 GHz Memory: 32.0GB Unknown @ 1197MHz Run time: 1 min 46 seconds I was doing some CAD stuff whit Solidedge and Teamcenter while solving.
-
Yes, as I said before in the post, was meshed with Salome. Normally I mesh one face of the perfil (or half/quarter in case of having simmetry), then import in a empty Mecway file, do the mirrowing if is needed and apply material and save in the Mecw…
-
No, I can't. Sorry
-
In the past had used a pendulum test as a way to determine the rebound properties of rubber, others ask you for a drop test as you perform, but inside a plastic tube to avoid wind effect. But for more accurate damping measurements we use dynamic tes…
-
Have checked and not, it doesn't go up higher than initial height. Plotting the position of one node is not accurate as the ball start to rotate after a few rebounds. Atacched is the model that I have run in CCX (using Scite to launch the solver) an…

I did some comparations between Abaqus and CCX using exactly the same cards, and the results were different after the impact. CCX bounds more than Abaqus, didn't find a way to change this behavieur even using different damping options on CCX.
