  • This is still a limitation - having constraints adjacent to the bonded contact. A couple of ways around it: 1) Prefer to put the master face near the constraint rather than the slave. It's more permissive but probably won't help in this case. 2) Ext…
  • Glad you solved it OK.
  • Oh yes, it's new to v3.
  • Hello protontim. No, the dynamic response analysis type in Mecway is currently linear only. With v3, you could export to .inp and solve with CalculiX though. In that case you'd probably need to make some edits to the .inp file manually but the mesh…
  • Yes, that's right. Both businesses have an agreement to sell the product based on the same original code. A few of the additional features that Mecway has are: - Both 32 and 64 bit. Much larger models can be solved with a 64 bit computer. - Fully u…
  • Oh, yes. MPEG export is only in version 2 and later. An alternative might be to use a screen capture program like Screencast-o-matic.
  • Hello Louis Yes, there's a separate menu next to the play/pause button for the transient animations, as shown in this picture.
  • A hinge is a little tricky to converge because it's underconstrained at the first iteration. A couple of ways are: 1) Use time steps (specify time step info in the global properties) and apply the force to stiffen the structure at a time before any…
  • Some people may have a valid concern which is perhaps not easy to ask - If I die, will customers be left empty handed? This is true about the technical support. However as prop_design says, the software will continue working as long as you have a co…
  • Good question. This is always an issue for large displacements. In Mecway, all loads remain defined relative to what they were originally defined on. This makes some of them follower loads and some not. For example: Force on a node is specified in …
  • Hello havsula It will have some sort of new contact in version 3. I'm not sure about large strain, but eventually I'd like to do that.
  • Actually, node coordinates are treated a bit differently from other values. They're displayed with whatever units the software decides you want at the time. For example if you use pounds and inches for material properties and loads, the tape measure…
  • Yes, any combination of units is OK so you can just look at the units shown next to a value to see what they are for that value but others might be different. Internally, it converts everything to a consistent system for solving.
  • Hello protontim The node numbers in the liml file have to refer to nodes that are defined in that same file. Even if the node is defined, when you use "Load into model", it'll renumber the newly imported nodes so they don't conflict with the existi…
  • Since this is a linear static analysis, all forces act as if the blade is in the undeformed shape. The centrifugal force doesn't try to straighten it when it's bent by the lateral forces. You would have to do a nonlinear analysis for that. Unfortuna…
  • Hopefully. In the mean time, you might be able to extrude shells into solids. Quadratic solids (especially hex20) are quite good with very high aspect ratios, but it might lead to a very large slow solve with something as thin as fabric.

  • You can simply merge the nodes, yes. That will create a hinge joint because an individual node of a solid element can't transmit moments. If you want a stiff joint, for now, you have to connect the shell across several nodes so that together they p…
  • What I quoted is pretty much the entirety of what Rao says on the subject of EM. The rest of the book is still a good description of the finite element method applied mostly to structures. I hope it's valuable to you.
  • Hello Protontim I don't know much about EM modelling. Though apparently [1] you can use the Helmoltz equation which is what's solved in the 3D Acoustic Resonance analysis type. For EM waves with permittivity = 1, set speed of sound = speed of light…
  • Indeed! It's not quite the same as suppressed (they are still included in the solution) but, yes, it does need to show that somehow. I'll see what I can do for version 3.
  • Hello apadzak Sure, there is no restriction on commercial use for the free version. For some people only making frame structures, 1000 nodes may be enough.
  • Hello apadzak The large deflection in the support is because it's made from truss elements which have ball-joints at each node. Change them to beams by selecting the elements then right clicking one of them and choosing Element properties. Uncheck …
  • Rhoka, importing solution values is something others are interested in too, and will certainly be a useful feature, so this is much more likely to appear, even though it still leaves some manual data copying steps for Wood & Armer. Apadzak, tha…
  • Thanks for the suggestions, rhoka. Most of these are more specific to civil engineering which isn't the focus of Mecway. Nonetheless, I do see they have more general value, especially 1,2, and 4 so they're not ruled out. Number 4, rigid links might…
  • No worries.
  • If I understand you correctly, you could start with the circle that you did, then extrude to get a straight leg, use revolve for a circular bend then extrude the new end faces to get the other straight leg. That avoids having to make any sweep paths…
  • Hello VMH Another way to achieve what you ask may be using Move/copy with the copy option turned on. You can press Apply repeatedly to make a line of nodes.
  • Hello Max Yes - using the Thermal Transient analysis type: 1) Select the faces which are to have this varying temperature 2) Apply a "Temperature" constraint by right clicking Loads & Constraints in the outline tree 3) When you set the properti…
  • Hello RobP You're generally right, just to confirm: The U coordinate is in the direction from nodes 1 to 2. All the beam stresses are longitudinal. That is, it doesn't calculate any shear stress due to twisting or shear loading. However, since th…
