[chrono] Re: Failing to build Chrono

Can confirm, CUDA 12.5 was the problem. I downgraded to 12.4 and the compilation for all demos was successful. It would be great to include suggestions on the version of CUDA to install in the installation guide, as you have for all other software that's needed. Thank you very much for the prom

[chrono] Re: Failing to build Chrono

1. I hadn't thought of it as an either/or case. I believe I need MPI to build and use the Vehicle module, for a few simulations with tracked vehicles. Please tell me if I'm wrong here. 2, 3. Even with all modules unticked, I'm facing the same issue. 3, 4. I've attached the cmake log and cache to

[chrono] Re: Failing to build Chrono

P.S. as mentioned in other posts CUDA 12.5 is not currently working fine with Chrono so you may need to downgrade to 12.3 or 12.4 or wait for the appropriate fix to Chrono (in the coming days probably) Thanks, Dario Il giorno venerdì 14 giugno 2024 alle 23:37:54 UTC+2 Dario Mangoni ha scritto:

Hi, - do you *really *need both MPI and CUDA? - does a simple plain compilation of Chrono *with no modules enabled* work fine? - which modules did you enable? Can you please *share the CMakeCache.txt* inside your build folder? - you are showing errors during *compilation*: was

[chrono] Failing to build Chrono

Hi. I'm trying to build Chrono. After facing issues in setting up MPI on Windows (Package 'mpi-c', required by 'virtual:world', not found), I switched to Linux instead. Problem: - I followed the first 6 steps of the Installation guide

Hi Radu, Thanks for your reply. I need to use version 9.0.0, so I took the tar.gz release from GitHub. Do you know how I can enable the submodule in a release src directory? Thanks in advance, MDP P.S. Sorry for the multiple replies, I was confused about using my email client or the web inter

RE: [chrono] Running Multiple Chrono Simulations in Parallel

Jared, A couple of quick observations. What you are asking for is not directly related to Chrono. This type of parallelization is what’s called HTC (high throughput computing) as opposed to HPC (high performance computing). The way you set up the multiple, independent parallel runs (multi-pr

RE: [chrono] Visualization for added collision shape

Visual assets are separate from collision assets associated with any given physics item in a Chrono model. You will need to create a visualization model that includes shapes corresponding to your collision model (although you do not always have to match them exactly) and associate that with the

RE: [chrono] Problem with the physics of the distance traveled by a robot

Better yet, please provide an example reproducing these issues that is based on a Chrono demo and model. That will make it a lot easier for someone else to debug and provide an answer. You could use one of the rover models (the Viper is already available in Chrono, including a demo of that rov

Re: [chrono] Re: Problem compiling ProjectChrono on Linux with CUDA 12.5

Hi Dario, Thanks for your help, got it. I tried then with version 12.3.x of CUDA but it seems there's a bug with Ubuntu 22.04 related to the DKMS build of the driver (https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-545/+bug/2065139) so I finally used version 12.4.0 and the co

The ‘chpf’ package is used as a git submodule. You need to initialize and update the git submodules in your clone of the Chrono repository. --Radu From: projectchrono@googlegroups.com On Behalf Of MDP Sent: Thursday, June 13, 2024 10:19 AM To: ProjectChrono Subject: [chrono] Re: Problem compi

RE: [chrono] Implementation of a vibrating system

You can use a linear motor with whatever activation function you want (at position, velocity, or force level). See demo_MBS_motors for examples. Alternatively, you can use a weld joint (ChLinkLockLock) which allows specifying a motion function along one of the constrained DOFs. See demo_MBS_

Hello everyone, I'm trying to simulate the behaviour of different non-spherical particles under varying gravity and some physical parameters like friction and restitution coefficients. I've modelled an open cubic container for the particles which rests on a reference floor which is fixed. I sh
