Sometimes for a huge mesh like I imagine that is your case, CCX PARDISO shows me as a succefull run, but not results are stored, this is due to the fact that you don't have enough RAM memory. You could try using the internal Mecway solver, that will…
I would sacrify a little of accuracy using half, or cuarter part if the loading is simmetric, best would be an axissimmetric model. Looks like your elements has not the best shape, I have a feeling that bad shape element can increase the time to sol…
I'm using CCX 2.17 with Pardiso, but as far as I know is "in core" version, that will try to fit all the model inside RAM, there are other cersion "out of core" that put some part of the model in disk if RAM is not enough.
Hi @disla , as far as I know all the postprocessors that I have used shows this same issue (look in Google images of FEA of shafts, and lots of them will show in this way, probably the ones that are not use less scale). Guess that is related to the …
Has somebody experienced the fact that a big problem was succesfully calculated (according to the CCX log), but there are no results at all? Today I solve a lineal problem that took about 30GB (of 32 available, all the rest was for Windows and Chrom…
Thanks @JohnM , have solved decreasing the scale of magnification, initial was x1000 but with x50 is enoguh to see the rotation and the other deformation is almost invisible.
@Victor, using the beta version, I have defined a quasi static no lineal analisys, but this definition is not keeped when I open again the analisys definition window. Have closed and reopened the model/program and the problem remains.
EDIT: my mist…
Hi Victor, what a bunch of new features!. Have tested the hardening curve, and found a little weird that the Young modulus be defined from the points of the curve and not as the usual way of taking the first part from the defined Youn Modulus and on…
Hi @cashan
1) Yes, using the the CalculiX solver, but the material must be defined using CCX Custom cards, not in the Mecway material definition. Look in the CCX manual how the material is defined at different temperatures.
2) Normally I made a the…
Hi Victor, maybe for future releases, can you add the possibility of grouping componentes in the model tree? Something like subassemblies for easily navigate (by reducing the lenght of the component branch), manipulate (hide/show related sectors of …
@prop_desing, that´s means that a CCX version compiled with this new compiler will be fast than the same using other one? And this compiled version (executable) can be distribuited also, or there is some kind of licence that avoid it?
Normally for selecting nodes, I hide the element faces, then with box selection the hided nodes (those aligned with one in front) are selected all at once.
You can define group of nodes (named selection) before solving, and then in the table result window select the results that you want only in your node group.

@Victor, in the mesh definition, the units once defined are not keeped between parts, so it must be adjusted for everyone. Would be greate to have the mesh definition stored similar to a material, so we could apply it for several parts in the model,…
@Victor, have tested a few minuts ago the internal default Netgen mesher against the last standalone version, and activating the multi thread option in the standalone there is a big difference in time to mesh (didn´t measure, but something like 10 t…
Hi Victor, can you add the possibility of generate named selection of CAD faces, but with more than one face? Now is possible but limted to groups of one face only.
Edited: Actually it´s possible to create named selection of several faces, even fro…
@Disla, is very easy to convert a shel mesh into a 3D hexa dominant in Mecway, just extrude the faces towards the thikness direction (+/- element normal), define the thikness and number of layers.
Dculp, you can do a mesh refinement based on a node directly, no need to touch the geometry. When you postprocess, select a node with high stress, and then in the contextual menu there is an option to create a mesh refinement in that specific positi…
That was the problem, I start with a modal analysis to check that all the parts of the assembly stay glued, and then change to dynamic response analysis... one hour solving and have finish without velocity results.
I use something similar, by means of the RIGID BODY card to atach the movil nodes to one pilot node, then apply the bc and ask the reactions forces to this single node.
Dave, the NODE PRINT cards by default gives you all the time increments and steps, there is a modifier to made every n increment.
About your problem, guess that you miss to attach the file.
Hi @DaveStupple, what I do normally in these cases is define a node set "MOVIL", on the upper surface of the movil part, then create a custom CCX card with
*NODE PRINT,NSET=MOVIL, TOTALS=ONLY
U,RF
CCX will create a separate .dat file with the data…
You could try to teach to you CAD team to design with FEA in mind, leaving small features as small radius, chamfers and holes to the end of the model, so is easy then to export a simplified model for FEA without need to further simplification or def…
