Set up a custom model input with *INCLUDE,file=input.inp. Click the appropriate CCX "don't includes" to suppress your contact commands Use Table to capture key outputs. Include a "save model to" as well. Create an input.inp that…

Modeling solid bolts is worth the effort. It's possible to model a fairly coarse solid bolt that behaves well. Use the Library feature to keep pre-built bolt models handy. You can import, rotate, drag into position and stretch pretty easily. You …

Nice.

It's the best way to demonstrate the undo function

You may find it worth your while to look at OpenFoam for fluids. It is open source and extremely powerful. Some useful links: blueCape Windows-based version http://joomla.bluecape.com.pt/index.php?option=com_content&task=view&id=95&It…

We use Mecway to perform basic fatigue analysis. The slide and notes attached shows the basic idea for high-cycle fatigue for typical engineering materials. I don't expect this to be the "lock" on how to do this, but it is a good start. Our curren…

That's great. I have to admit this thread forced a conversation with Guido, and I wouldn't have known about the fix in 2.16, so good for everybody You might check out the CCX command *INCLUDE. It allows you to point to a file as input (that in yo…

Models must have only volume elements, model and submodel must be same CCX version. If that's not the problem, I would try running in 2.10 or 2.11, to see if it's a new bug, other than that, it's time to submit to the Calculix forum.

see this thread http://mecway.com/forum/discussion/750/propeller-hub/p1 The method I suggest (see 3rd-4th entry) is not the onlyway, but it is simple and works. I have upgraded to 2.16 and it works fine.
-
Good news. Guido has informed me that CCX 2.16 has fixed the submodel issue, I just tested with pardiso216 and it worked perfectly.
-
There's some kind of format error in the newer versions, I think I'll try and resubmit the bug to Guido
-
It's actually pretty straightforward and also a nice example of how to use CCX commands to get more out of Mecway.
-
Build your fine submodel in the same space as the coarse model, then delete all so that the only thing you have in the Mecway database is the fine mesh model and a node set called cutb. Add CCX custom stuff below. You will also need to set the Mecw…

MESHING STAMPINGS/SHEET METAL Parts with a single thickness (like sheet metal) can be meshed with hex solids by first meshing quad shells, selecting one surface, and extruding through thickness. These models are usually smaller and better quality. E…

I have heard your exact comments from other forum users, that's why I started this thread! Here are two slides from some old group notes using GrabCAD examples. It would be great to understand what I don't know about Netgen. I have found Salome to…

Your c3d error is likely from elements becoming distorted when they projected onto the adjacent surface. Make sure you are bonded contact pairs are closely mated. If you are using at *TIE command check the tolerance you are using between the surfac…

I increasingly find myself relying on GMsh rather than Netgen. Very often the Netgen mesher gives me too much detail where a few splines have come together, and often does not produce a mesh when GMsh does. I do wish the refinement features that a…

The library feature was hidden in labs in V12

Python API test - save this as modY.py select nodes, execute macro, input new Y value (m). It works! def mod_node(nodes, value): for point in nodes: mw.set_node_y(point, value) active_nodes = mw.selected_nodes() # Get selected nodes i…

I can right-click select now, no flicker on top, looks good.

This was a feature that started as a Lab request. If you open a blank Mecway, define a single property, then save, you have your first property. If you switch around to the different physics, you can get "everything" in there - thermal, plasticity, …

I'm hopeless with Python but one of the guys wrote a quick example that takes the centroid of selected nodes and writes to a file. Works great. As soon as we do something useful we'll share, looking forward to everyone else's use of the Python API! …

I didn't think there were enough versions of how to mesh a DXF file, so here goes mine. Two minutes to click the nodes in one half-section to create quads, mirror, copy, copy,refine. See attached.

Intel Xeon CPU E5-2698v4 2.2GHz 64GB 2min 13sec ccx 2.16 PARDISO using 10processors out of 40 ~6%CPU reported

I'd like to say that was deliberate - it's just the machine we bought 4 years ago that "made sense". In the past, I have benchmarked mult-processor speedup, with spooles on CCX2.8. I found that 8 processors was the point of diminishing returns, …

We will bounce a ball to get the damping characteristics of the material. Connecting the peaks forms a curve that allows you to calculate damping from fitting a logarithmic decrement.
-
I have some suggestions for you: Start small - work out the details on a "single bay" model. Extending to 4cyl can be accomplished by applying the phase angle (180deg) and firing order(1-3-4-2). Start with constant speed. To develop the pin loads…

I ran a chunk of your model with a single strap - it looks like yours. If you use displacement scale > 1.0, the deformations for a contact run can look silly. for example, if 2 parts come into contact by part A moving right 1mm and part B moving …
