FSI Module Build Errors

[Vanessa Hernandez-Cruz]

Hello, 

I am trying to use the CRM terrain model associated with SPH. Previously, I was working with SCM terrain to model regolith. I uninstalled my original version of Chrono since I followed the instructions here : https://api.projectchrono.org/module_fsi_installation.html . However, I get an error that "ChronoEngine_fsi has been modified outside the environment". Does anyone know what could be causing the debug build to fail or how to fix my error? More details can be found in the screenshot. Thank you in advance.  

Best,

Vanessa

Hello Vanessa,

From the error message in Visual Studio, the reason why chrono_fsi didn't build a third-party library, chpf, is missing. Take a look at this post, and I believe you can use powershell for the git submodule commands.

Once you have fsi built successfully, you can Reload All in visual studio.

Note that when you set up cmake, if you want your FSI simulation to run fast, you can use single precision, and set the "USE_FSI_DOUBLE" flag to be "OFF". If speed is not a concern, and you want to go with "double", which is what the installation guide said, please use the latest code in main, I just pushed a fix earlier today.

Thank you,
