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…
-
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…
