hi, this is very urgent.
i have a 3D model of blood vessel where blood flows inlet to outlet and interacts with solid objects in the center of the blood vessel. but in the cfd-post, it shows that blood passes through the solid objects without interacting with it as if the solid domain is not there. i have already defined the solid domain in the cfd-pre but i havent set up the domain interface bcs of errors of overlapping boundaries. how can i fix this? :'( |

Hello,
Make sure your contact surfaces between the fluid and solid domains are well defined and without overlap. Sometimes it can be useful to check each boundary and adjust them manually so that they match perfectly. Remember also to check that your boundary conditions are correctly applied to each interface. A bit like a synchronized calendar where every event must be perfectly aligned to avoid conflicts, your domains must be well defined for the simulation to work properly. |
