  • Hello There's no convenient way at the moment. The closest would be VRML export which has the color contours. However that's an obsolete format so it might be difficult to find tools to get it onto BIM software. Is there a specific file format tha…
  • For Automesh 3D, the min. elements per edge and curve, and size grading aren't available like they are for STEP files. I'm not sure why offhand - probably not supported by the meshing library. So to prevent many tiny elements, you would need to rem…
  • Hello saco It doesn't have that functionality. However whenever new elements are created by most of the meshing tools, they're automatically selected so you can right click the component you want and choose "Add elements"
  • Thanks, I think I understand now - For gasket reaction, you can turn off visibility of the flange's component(s) in the post-processor (right click the component under Solution, uncheck Visible), leaving the gasket visible, then it'll show the stre…
  • For bolt pretension, you could use thermal stress to apply a pretension force on solid elements. Alternatively, if you aren't interested in the details of the bolts you could use a spring element with a specified free length so that it's pretensione…
  • Hello mattone As delta says, it will be easier with a file to look at. I suspect this is going to be difficult though. Since the nodes are not coincident, there's no generally easy way to join them. Some possibilities: A) Manually move them to be…
  • Hello Sture. Thanks for the suggestions. I've added all those to my own list. There is an undocumented way to obtain shear force per unit length for shell elements. However, the results are sometimes misleading and need to be interpreted appropriat…
  • Hello JesusBarreraA Sorry for the hassle of this. Can I ask what version of Windows you're using? .Net Framework 4.0 won't always run .Net 2.0 applications so you should also install .Net Framework 2.0, available here http://www.microsoft.com/en-…
  • Hello delta This is a difficult problem if the different meshes don't have the same pattern of nodes and faces on their connecting surfaces. Being "components" in the outline tree has no effect on their connectedness. They should share the same no…

  • Thanks for the suggestion about edge refinement. I'll keep it in mind for possible future updates, but can't promise it. For now there's only the spherical local refinement, so it might take several of them to cover a linear region. Also, you can re…

  • Hello tcarson All 6 orthogonal views are available by left or right clicking on the triad arrowheads. If it ends up upside-down, use alt+left/right arrows to rotate it. Regarding the edge refinement. A less convenient way is to add a string of loc…

  • Hello saco 1000 nodes (not 1300) is the only restriction of the free demo version.
  • 1) The longitudinal stresses (caused by bending and tension, not shearing or torsion) are shown at 4 points on the section of each beam. These are listed in the outline tree as Longitudinal Stress Point 1, etc. Click the plus next to any one of thos…

  • Hello mattone Mecway's STEP import can only mesh a single closed solid shape. So a shell won't work. One way around that is to change it into a solid (ie. fill in the interior of the vessel) using your CAD program, then generate a surface mesh in M…
  • Hello Tim Yes, you can do that. Simply connect the elements together and they'll transmit moments as well as forces between each other. Here's an example of a 3D frame structure. For non-symmetric cross-sections, you'll also need to define the ori…

  • No, it doesn't have that feature. You could do something similar with stiff shell or beam elements laid over the surface to accept point moments and distribute the load, but that takes time to model. My preferred way is to simply use two point forc…
  • Interesting comparison. I'm surprised the results are so similar! Since these are solid elements, it's to be expected that the linear hex8 model doesn't deflect as far because those elements are unphysically too stiff in bending. You would usually n…
  • Mecway isn't well suited to the kind of multi-step analysis because it doesn't have the concept of arbitrary steps. If it can do this in future, it'll probably be manually controlled - do one solve, then another, then combine the results.
  • In this case, force on either faces or nodes will be OK because the total magnitude and direction is determined by what you specify and won't change during the solution. There's an undocumented way to output strains but it won't be accurate for lar…
  • Material non-linearity is certainly on the radar but it's not a very popular feature so may be a while. However version 3 will have Abaqus/Calculix file support allowing you to use the Calculix solver which has plastic and hyperelastic materials. C…
  • Hello Jacinto 1) Mecway doesn't have any failure models so it's not specifically for ductile or brittle materials. The non-linear analysis currently only includes geometric nonlinearities like large rotations, stress stiffening and buckling and doe…
  • Hello Janko While this is possible, it can be a little tricky to specify the boundary conditions. Use the 2D Navier-Stokes analysis type which allows velocity boundary conditions for a no-slip condition at the cylinder. Here is an example. As you …
  • I'll add this to the list. As always I can't promise but thanks for suggesting it. Are you also looking for the internal contour surfaces?
  • Thanks for the suggestion. This is a widely requested feature, so I'm aiming to get it into Mecway in a near future version as long as there are no major obstacles.
  • Hello VMH Typically, if you've used imperial units in the model (except for the mesh if you reopen the file), the tape measure will show inches. It could be that it contains some metric lengths or no imperial units at all. A workaround is to start…
  • Thanks for the suggestion. I can't promise temperature dependent mechanical properties though. For now you would have to do it manually using components to define regions of uniform properties.

  • Hello apadzak I think this is not a problem, just a difference. By refining the mesh several times, it looks like the "true" mode 9 should be out-of-plane as you found with Mecway. In that case, the hex8 elements in both Mecway and Abaqus are incor…

  • Hello apadzak I recognize the limitation of not being able to select edges. However using nodes will give exactly the same results as edges because edge constraints would be internally converted to node constraints. I'd be interested to see the mo…

  • A few hundred or thousand, depending on what features you're interested in. Maybe down to 100 using hex20 elements (hand-made mesh). I notice that in this case the stress away from the fixed support mostly changes by less than a couple of percent wh…
  • These two files are identical (wrong upload?). Mesh refinement will probably have a big effect on them though because they use tet elements which can need a lot of refinement for good results, especially when they're so distorted like that. You don…
