Since this thing is unattached until it is (through contact), use a very small time step initially, and let auto time step do the rest. You might also need to use an elastic support with a very low stiffness to give the pile something to make it s…

I converted to solids, moved the straps up so that they start with an initial penetration with the pile wall, starting time step 0.01, used auto-time stepping, ramped the gravity. The straps start out very "soft" until they develop contact, so a lot…

In fairness to the person who taught me this trick, search YouTube for "calculix hyperelastic" to see the example. Interestingly, it is also a bellows!

I copied all of them of it, about 500MB into my PARDISO directory, and saw another significant improvement. Worth the disk space!

how many of those DLLs are there? Maybe I have to break down and learn the right way to do this! Thanks for finding this, I'll be testing myself!

PARDISO is nicely hidden in plain site on the Calculix website. On www.dhondt.de, look for Windows executable..... files Download the Intel MKL from here https://software.intel.com/en-us/mkl/choose-download/windows Run with ccx_pardiso solver, it …

I keep several ccx solvers in the same directory as my default, using directories when necessary (as with PARDISO with all the dll stuff). The current version bombs with the SUBMODEL command, and some versions don't play well with the KINEMATIC stu…

Not sure of the issue, but for reference, I am running Mecway12 (but should work in all), and Windows 7. I downloaded the zip file, extracted, double-clicked run.bat and it seemed to run fine. Below are some details The run.bat file -creates the …

When running many variations on the same model, consider running in batch: 1- set up and run model with all unit loads, set Mecway to output a scratch.liml 2- edit *.inp to capture the load files in a file called unit_loads.inp 3- add *AMPLITUDE ca…

VMH, I'm not sure we're supposed to share that way, but if you install the Intel MKL and then look for those files (I've screenshot so you can see the date stamp and file sizes). You will set this up quick, promise.

This is why forums work, you get back more than you put in We run multi-core, although the biggest speedup is in the first 4, and by 10 it's not worth it. Note, this plot is based on SPOOLES, NOT PARDISO, but I suspect a similar behavior.

Nice. If you haven't already tried it, now might be the time to give the PARDISO solver a go. I have found it runs in about 55% of the time for SPOOLES, and seems only limited by the machine memory.

Looks like the Library might be getting out of Labs soon
-
Hengre- Check out the "Import from Library" feature that can be enabled in Labs, it lets you use your idea to great effect by keeping material files in a common place for your team.

Thanks for catching that one Victor! Take a look at your *.inp file, cut and paste the *MATERIAL cards down to the first *SOLID card, and put into the "custom model definition" option in the CCX tree. Use the "Don't generate" option to suppress the …

Run a dummy thermal through the depth of your foundation, so that your temperature is run from let's say 0-1C. Transfer this temperature field to your structural analysis, then use a temperature dependent E with the desired variation. Make sure you …
