I don't know if this will be of any use. Scan and Solve has some material properties you can download. I attached the download they offer for plastics. There are some glass filled plastics in the database. Scan and Solve also has a lot for wood and …

I don't have any working knowledge with the GRP material. The only suggestion I would have is MatWeb and Google searches. Sometimes you can get lucky with either of those. Generally, quality material data is hard to come by for free.

interesting comparison 3rav. victor actually suspected this from viewing their website. the examples they used to show a speed-up were not relevant to what we use it for. nice to have confirmation though.
-
i'm not sure about compiling it yourself. i would think it would generate the same thing. but victor would know more. using the ccx_pardiso_dynamic definitely allows for faster solves and much bigger models. that much i can attest to. i have never t…
-
both methods you ask about use the same pardiso version in the intel mkl. the bolt assembly was something i made for a forum user, to try and show how to apply a bolt load. someone else started using it as a benchmark.

hi, i do fatigue analysis with mecway. however, i didn't respond to your post because you are doing things i haven't done. i have several videos on youtube showing how to use mecway. they include fatigue analysis. but again, probably not gonna help…
-
Yeah I haven't followed CCX development. I'm not sure if it is new to 2.16 or if has been there awhile. From the website, I got the feeling it was new for 2.16.

I updated most of the screencasts recently. Mecway v13 beta was used.
-
hi john, i believe i tried salome once based on sergio's posts. but i too did not like it for the same reasons you mentioned. i have tried gmsh many times but have not liked it. it was crashing a lot. the latest version hasn't crashed on me but i c…
-
it looks like you need to add stress stiffening 'AND' constrain the model. It can't get stiff without a restraint.
-
it does say it supports gmsh and netgen mesh formats though. the documentation doesn't seem very in depth.
-
yeah, i have never seen curved edges either. it can make a mesh that follows a nurbs surface. somehow they are showing solved examples of that. but as far as nastran, ansys, algor, i've never seen that.
-
I found this open source library that looks interesting. It also has solvers. https://mfem.org/
-
so on one model i tested i got a 20% speedup. this was comparing 1 core to 2 cores. all mesh settings were the same. my laptop doesn't keep a consistent speed. so any multi-core testing is impossible to predict or understand. but still, 20% is nice.…
-
Update: There's an article that they posted awhile back, that states you can expect about a 3x speedup. https://ngsolve.org/news/new-features/52-netgen-parallelization I didn't time it, but it definitely seems a lot faster, even with two cores.
-
both models should have .375" diameter holes in them. i'm not sure about creating a grid with nodes. you can use the plate feature to make the midplane model with holes. that will have all quads. but doing all the loads is a serious pain. selecting …
-
yeah, it's a lot easier to do this as a solid. you can make geometry selections, which is what speeds the whole process up a lot. i attached a model you can check out. i tried to simulate the screw/bolt connections at the holes. i used a .5" washer …
-
it looks like it's easy to create the plate with holes using mecways built in tools. but when you copy the initial geometry to make the plate, it messes up coping the loads. so it makes applying loads a real pain. i gave up on it, due to the time i…
-
I have the opposite problem. I can't get gmsh to give me detail where i want and it gives too much detail where i don't want.
-
oh ok. thanks
-
interesting result. for solid models the node limit is around 160,000 compared to 90,000. the 600,000 and one million node limit was for laminates. apparently there is a big difference in what type of element you are using. but it's still an improve…
-
It looks like the features I was referring to are new in the V13 beta. I don't see the same capability in V12. That makes me feel a lot better. I thought I missed this awesome new feature. I changed my files around to make use of the new library imp…
-
so i've been kicking the tires on the v13 beta. lots of improvements. i was limited to around 90,000 nodes on this laptop. now i can go over 600,000 nodes. i ran one model close to one million, but that starts too get too slow on this computer. very…
-
Thanks John, You have really made great use of this feature. I will tweak how I was doing things. Previously, I had templates and would import them with file import. I hadn't noticed the library menu feature until now. That makes it a lot more conv…
-
Thanks a lot for the updated Beta version. The E3 feature is great for laminates. Also, the transfer displacements to mesh override works for laminates now. I compared laminate to shell model and got the same result. The fix for OMP_NUM_THREADS work…
-
i tried the new beta version, changed some mesh settings, and used Netgen toggle instead of the Netgen 6 toggle and didn't get a problem this time. I'd like to get the error back to see if it will show the bad elements.
-
i tried the button you mentioned but it wasn't showing anything for me. i was using the beta version. i need to download your new beta version. i'll try again. thanks for looking into it.
-
@victor, If you get a chance, the test2 model won't solve when using quad dominate option. it says there is an element with zero width somewhere. the option to try and highlight which element that is doesn't seem to work for me. you can mesh it wit…
-
@famous_mortimer, I noticed the curves are broken up in a lot of weird ways. I tried to rebuild them but it didn't help much. I also tried recreating them, but that was problematic. It seems like, when I import the dxf file into Rhino 5, it's not t…

here is a picture of a dimension in millimeters. not sure what the size of the model is. i may have an import problem.
