I've been trying out Cubit (the free version) for a while now (I posted about it a while ago but no one responded). It is the best tool I've found so far for hex meshing. I would judge it a bit less complicated to learn than Salome Meca to use. I…
-
One thing I noticed when I imported the inp file.....I had to use a cutting plane when I set up the hex mesh in Cubit to map elements properly. After meshing, I exported the mesh and imported it into Mecway, where it came in as 2 bodies. Is there …
-
Victor, I did get the abaqus.inp input to work OK, I'll try the I-DEAS format as well. It does a slick job on hex element meshing, and is much more intuitive to learn on the fly. 50000 hex elements is plenty for my purposes, plus the Mecway refine…
-
Cubit used to be Trelis, but now Coreform markets it, and they have a free 50000 element version (for hobbyists and students), which is what I used. I tried the Abaqus (inp) export but gave unexpected results.

I finally found the latest version of the solver being discussed (3rav) and tried it on the benchmark bolt assy on two different machines with the following results: PASTIX+PARDISO, OPENBLAS_NUM_THREADS=1, PASTIX_MIXED_PRECISION=1 MW+ccx2.17 Intel…

Where exactly is the latest Pastix compile for windows?
-
Is there some sort of recipe for compiling this solver similar to what Victor gave us for Pardiso? I'm wondering how the current compilation was done.
-
OK, guess I'll wait too
-
Oh. I was curious where mmartin got the brand new compilation he refers to and if it was available to install on Windows in his benchmark run above. Knowing where to get that would be very useful.
-
Where is the compiled version of Pastix? All I see on the Calculix page is the source code to be compiled.

Hi all I ran the calculation on Mecway 13.1 with ccx 2.16 pardiso as follows: Hardware configuration: CPU: AMD Ryzen 9 3950x (16 core/32 virtual processors - runs at about 4.2GHz RAM: Crucial Ballistix UDIMM 32GB clocked at 3200MHz SSD: Samsung NVM…
-
prop_design, thanks for the clarification. I would have given you credit but I couldn't recall who originally generated the model. I asked about the compiled ccx_mkl because Victor indicated that if the instructions were followed, as I did, that i…
-
I managed to get the compiler to build something, and got the following in the ccx/src/x64/install folder: 1. ccx.exe 2. ccx_MKL.exe 3. Various llibxx.dll, mklxxx.dll, pthreadGC2.dll, and license.rtf I noticed there were no mkl_vml_avx files as su…
-
OK, thanks Victor. I also noticed that you want to copy some MKL files into ccx/mkl, but I show mkl in ccx/src/mkl.....correct? Please also verify the correct path for the final compile to be ccx/src
-
Hi Victor, I'm trying to follow the build instructions for compiling the large model ccx you describe in option 4 above, and have run into a couple of snags (I've not done this before): 1. There is no ccx/src/etc/ directory, but there is a build.sh…
-
Victor, which version of ccx is standard in Mecway13, the std ccx or pardiso?
-
Solver: CCX Pardiso v2.16 CPU: Intel Xeon W-2123, 3.6GHz, 4 cores, 8 logical processors/threads Memory: 16G, 2666 MHz Run Time: 1 min 43 seconds
-
Sergio, Sorry, I did mean Gmsh 5.0.
-
I will say, though, I'm really looking forward to Mecway using CCX's upcoming implementation of Hextreme, when and if it happens. Speculation is ccx 5.0.
-
Victor, believe me, I understand your comments about making Mecway a general PDE solver - one can only ask. Mecway is already excellent for the price. Please consider, however, at least adding formula creation for temp dependent variables. Prop_…
-
prop_design, I'm familiar with the packages you suggest, but flexpde in anything other than 1D student is expensive and still is scripted, and comsol is beyond expensive. It will be interesting what comes out in Mecway 13. cmmcnamara, I know Vict…
-
cmmcnamara, I understand I what you are saying about how thermal conductivity vs temp will work, but I want to just add an equation instead of a table of points to describe the relationship to Mecway, such as D = D0*(1+C/C0). This does not yet seem…
-
cmmcnamara, I looked at what you suggested, and I'm not seeing how I can do what I want to do. When I ask for temperature dependent thermal, it only gives the option to construct a temp vs thermal conductivity graph relation, and what I want to do …
-
This is interesting, but what would be really powerful would be to create the equations, BC's, constants, IC's etc. via the formula entry chart, for a custom equation/solution, and solve. It seems like most of software infrastructure is already the…
-
I have also used Salome to create hex meshes on STEP solids, then import the mesh into Mecway for contraining and solving with good results. You have to fiddle a lot with settings, partitions, 2D and 1D mesh controls (for 3D) and submeshes for regi…
-
I'm also interested if anyone has successfully created unstructured automatic 3D hexahedral meshes in Mecway, using any of the available meshes? I am just interested in if it can be done. There is something called Hextreme that supposedly was goin…
-
For the most part, yes, gmsh 4.2.1 works OK separate from Mecway, although I am not an expert in all of it's variables. When I try to create a mesh in Mecway using gmsh, checking the box "determine element size from curvature" and mesh a simple bar …
-
Anyone? Is it expected that gmsh v4.2.1 should work OK with Mecway?
-
Victor, Here's the text from the CCX output file for the problem I ran on your v.11 with the embedded CCX. Do you intend to test the multicore version against the problem areas you mentioned? I'd be interested in the results. BTW, the results fr…
-
Victor, I got Mecway v.10 to use all 8 cores for stiffness, spooles, and stress using the bconvergence v2.15 CCX. However, when I run the same problem in your newly posted Mecway v.11 using the imbedded CCX and the same environmental variables, I u…
