Hi, I'm doing some test with hard contact, and I have computed a value for the slope of pressure-overclosure, that make my problem solve. But now I want to start to try with different friction coeficcients, but there is a red warning in the tree tel…

Hi, I make the same, use an external program to take screenshots. Maybe could be implemented in Mecway a similar feature, a keyboard shortcut to use the actual save as PNG feature, thus there is no needed to implement the removal of the cursor and t…

I would add that every industry has his own criteria for meshing, posptrocessing and results, you should investigate on your customers about his FEA criteria. For example for automotive ductil parts is very common to have as accepted a V. Misses str…

In my experience hexamesh is a slow process and very manual, at least for complex parts. The first times that you mesh with bricks will take a time to understand the process and tools availables, and learn the mesh patterns for your commons features…

This is the same parte now with quad mesh in Roshaz and then sweeped in Mecway...the procedure was really straighfull, and now is full hexa. Guess that the next step will be meshing in IA-FEMMesh also.
-
Until we convince (hey, we need more people, please make noise in this thread!) Victor to add fully 2D quad mesh in Mecway, in order to have a full hexa mesh the parts (faces in fact) can be meshed (2d seed quad meshes) in Roshaz and then export to …

Hi, following with my tests of the extructured meshing in Mecway, I took the last example and add some radius to the bosses and the tube, places were normally stress will be concentrated and need to have a good mesh. I didn't put attention on mesh q…
-
Tomorrow I will try some parts with radius to see if it can be done. Regards
-
The first simple is the yellow, the second (not in the pics or model) was a try to make the next part with bosses and draft importing the solid (but I was not able to select the hiden faces), the third (grey) is then the same model but just only imp…
-
I have tried some simple parts, and for very simpe could work (see . I have added a little of complexity and then arise some troubles: 1) We need a wireframe view and possibility of select hiden surfaces to then invert selection and delete elements…
-
Victor, can be meshed only some faces of a imported solid? I meant, if this were possible we could just particionate the solid in the CAD in "swepeables volumes" and then in Mecway try to mesh some faces and extrude/revolve it. Maybe the end side of…

IA-FEMMesh export in Abaqus inp file, you can create even groups of nodes/faces/elements for creating boundary conditions, so is easy to follow the work on Mecway or CCX. I did'n try for mechanical parts yet, but the joint looks great.
-
And what about the cpu costs for including more faces in one side of the contact set? I came from old school where you must optimize every element and contact defintion to get the results as soon as possible, that I why I get the procedure of separe…

VMH, I work for the automotive markets and sometimes we are request to perform FEA on bolted unions under extreme loads, in order to address slip and gaping problem. We do a quick hand calculation but at the end we perform FEA for some sensible part…
-
Very good example VMH, just one point to notice, when you solve in CCX, you have two error messages about bonded contact converted to TIE. What is the differences between a bonded contact and TIE? On the other hands, should be this messages changed …
-
Hi VMH, very good example and nice video also! What are you using to capture this videos? By the way, I see the same issue when you postprocess as me. The first thing that you look for is the magnitude displacement (to check that the model is displ…
-
Can you share some samples of the parts that you need to mesh with hexas? I have being meshing with pure hexas since 2001, on I-DEAS and NX. Maybe I could give some advice. Regards
-
Hi Robert, just reading the complete thread, I realize that I'm in the same situation, complex hyperelastic materials, big displacements and contact everywhere. What I have found productive for simple parts is export the solid as IGS (faces) from t…
-
I have tried IA-FEMesh this week, for "biological shapes" works ok, I have tried a few simple cases (bones) and they create very amaizing full hexa 3d meshes with very few clics. This bones doesn't has sharp edges, I will try some more complex shape…
-
Hi, you can also use Onshape that is an online CAD suite, modeling is very similar to Solidworks or Unigraphics, and is free for small projects.
-
Hi Victor, have tried the procedure and works OK, 10:1 reduction time for creating the bonded contact features!!!! Thanks and looking forward to the next release!
-
Another new ones after working with assemblies, I found a little complex creating the bonded contact condition (when they are several). First I create two named selections with the faces in contact, then rename it (because as they will be several I …
-
Victor, for moments the results are not zero, you must do a RIGID BODY between the movil faces with two nodes as pilots, then aply the rotation in the second pilot node. The reaction in this node is the reaction moment (even if the .dat header says …
-
Victor, Abaqus CAE has a powerfull plot utility that allow you to look for all the variables that you has ask to save and perform several calculus on them (summarize, convert grad/radians, even apply some filters to smooth it, etc), then you can mak…
-
Guess that Stefanos refers to the nonlineal plot on the lower side of the Mecway window. I have also in the situation of need this data as text to plot on Excell as well. Maybe would be good an option not only copy as image, but also copy dataseries…
-
Hi VMH, look for the clip example in the Mecway installation folder, is a good example to start. I have to tune a little the first coefficient to work on soft parts. Regards
-
29) Can you add the option to merge (including a places to define the distance) nodes in the mirror copy mesh feature? Normally if you copy the mesh, 90% of times is to create a complete mesh, then will save a lot of time.
-
28) Can be added to the lower information bar the number of items selected? Sometimes is necesary to check if there are created two nodes in the same position (to control rotation dof's in a rigid body), otherwise I have not found a way to check it …

Hey, nice model VMH! As far a I know CCX expand the shells to solids, have you try to postprocess the results file (.frd) in CGX to see if you see as a shell or solid? For small models like that I preffer to use a solid mesh (extruding the shell in…
