• Simulation on weldment keeps crashing - instability issue

    Hello All, I recently was given the task of making a model of a crane that was designed on an old hard to read drawing around 45 years ago.  It oddly never had the tonnage rating on the drawing called out. ...

    Hello   I was wondering how to interpret the turbulence intensity parameter. From my research, it is the the amount of "fluctuating" flow in relation to the main flow. Still, I find it hard to interpret and set ...

    In one of my recent flow simulations I noticed something a little wonky with a definited contact resistance between two surfaces (K/W option). So I decided to make a basic flat-plate on flat-plate conduction-only mode...

    This might be a silly question, but I can't for the life of me find any information as to whether the Solidworks Flow fan boundary condition can be used with pumps instead? Obviously I would import the pump PQ curve &...
