Small boat with DBFI FLOATING POINT EXCEPTION
Hi
A friend of mine did a small examble of the small boat examble but he get a floating point error..... I create a better mesh but i do not know why he gets the same error ! ! ! do you think that we have to apply a very fine mesh in the sea level????? any idea? |
VOF and DBFI can be used in very coarse mesh (eg 50k cells is feasible to check everything is working - runs very fast) - just reduces the accuracy and ability to capture the waves. Check all you settings compared to the boat DFBI tutorial in the Help - it is very easy to miss one of the steps or settings.

In my help file there is not tutorial with the Boat, i just have the small boat model but i might miss of something,
can you provide me this help file? or is there anywhere online? thanks |
On the start page of your help, you will find a tutorials section (nearly at the bottom) where you should find a dynamic fluid body interaction node. The boat in head waves tutorial is a sub-node of dfbi.
All files necessary to run the tutorials are also provided with the ccm+ installation. Just open the installation folder and click through some folders - you will find it for sure. |
