I have been looking around the forums for a while and some topics come close but what i am trying to do is find out what, if any, software could do a piloting simulation of a custom design and not just a stock one. The reason for this is a few friends and I ware working on a design that isn’t that conventional and would like to be able to test it before manufacturing it, we currently have a digital build done in solidworks that has the mass, volume, ect… if that helps in something that can do the job. In the end all we need for sure is a program that can give us a simulation of how our rov will act rather than a stock design
