Load was wrong in my model. Thanks Andrea. Mecway divide the applied force load by the number of selected nodes. I made the same operation before imposing BC so my TOTAL load was less than required. First Principal Stress 202 Ksi Von Misses 187Ksi …

You are right Andrea twilliams55 comment is working in extension. Just comment I do not get contact between spirals in compression. Run again with new conditions ,ccx2.13MT, NL second order tet elements and obtained: -Von Misses 7.86 Ksi -Tensile …

What processor do you have in your computer? You need to add the system variables: NUMBER_OF_PROCESSORS="Max number of cores in your computer" (Should alrready be defined. I have 8) OMP_NUM_THREADS = "Max number of cores you want ccx to use" (I hav…

Hello, I'm getting different values. Two orders of magnitude difference but in line with PEEK compressive strength of PEEK. I have applied the 5lb distributed in some of the upper nodes 5lb/24 each one of the 24 nodes. I have left the spring free to…

Your model looks right to me. I think you are missreading the units. After Imported I use the Tape measure tool to measure and found that it the imported model was in meters and the part which should be .297" long was 7.5 inch long this is the pr…

There is an elegant way to impose this boundary condition as you want directly in MECWAY. I discover it not too long ago. I'm also rookie in Mecway. I use it for the tank bases or when I need a stiffening ring in a pressure vessel. Check the liml fi…

There is a trick to properly re-scale STEP file before import to MECWAY editing directly the step file with a common editor.(Notepad for example) There is a section in STEP file telling translator what unit and what conversion factor to use. Open S…

"Youngs modulus has nothing to do with the stress found in a material only the deflection present". Mmmm.. not agree. Equalities should be read in both directions. If you impose displacement as BC Young Modulus affects directly to the resulting st…

It works !! . Thanks Andrea and Sergio. Seems I’m closer to stablish a proper workflow. Tank's both.
-
"standard linear static young’s modulus of 206000psi, P ratio of .39" Is the Young Modulus Right?. I have found some internet references for Peek. P ratio seems in the same line but Young values are more than double (545342-572899) psi. Seems you ha…

I'm using Salome to crate the model and mesh. ¿Any idea why I'm failing to import beam elements as a step file.? I will try also Andreas trick. Thanks both.
-
Thanks Andrea, I will try.
-
I'm using gmsh-3.0.6.Maybe that's the reason. For me meshing on mecway with gmsh works but do not reproduce the same mesh as directly in gmsh.
-
kwip could be right when says "There has to be something with the environment ccx is started". Same file and same solver with MEC 7 and MEC 8 show an improvement in solution as I said on my previous post (now we have Symmetry). Andrea I remember you…
-
Not sure about your problem. Meshing tools menu operates on meshes and they are only accessible once the mesh is available. It need a mesh. Once you generate the mesh (right click step file in the tree view) mesh tools menu will be available when yo…

Of course Kwip. It is no more than a validation file to check software reliability. If you are able to solve it, that would be a beautiful Christmas present. Good luck. I found the same issue with second triangles. Refining introduces even more spu…

Be careful. With ccx_2.13_MT.exe use Buckling analysis carefully. Seems that for this new version solution with ccx_2.13_MT.exe could be right but with much higher number of elements than internal solver. On previous versions solution was not even s…
-
Thanks Andrea. I will look at. It seems what I'm searching for.

Hi Andrea. Thanks for the hint. You are right , it was meshed with Salome. I have been looking for "create node set function and I can’t find it neither forums or help files. ¿Is it in the mesh module.? Thanks in advance.
-
It works for me after some operations. Move all objects to only one layer. You can keep layer 0. Purge the model eliminating all other layers. Explode. Sometimes it fail to me also when the model is very far from origin so move the model to the 0,0,…

Good afternoon, I would like to use this example to make a question that has been around my head for some time. Excuse me if it is not strictly related with Mecway operation. I have read that shell/membrane elements are good elements to discretize…
