error messages about blockmeshing and solving
1 Attachment(s)
Good morning everybody !
I´m new on OpenFOAM, and I´m doing my master Thesis on this software. My Topic is about create an RTM simulation and validate the best solver I can use with.
I created a tank (at the bottom), a tube and plate (at the top) which is my composite.

I´m pretty sure this error has his root into the blockMeshDict but I don´t know where ! :confused:
I´m on it know for more than 3 weeks and I´m totally blocked :(
I used to go on this usefull Forum to fix my problems, but this time I need to ask your help ! :confused:
This is my first post ever here, I hope it is clear ! I upload the whole file here.
Thank you a lot for help, I begin to be desperate about my job :( |
