I am modelling wind flow around a structure and have got results which i am happy with for a wind angle of 90 degrees to the building face. When i rotate the model by 45 degrees and use the same settings the convergence criteria are not being met and look different to the 90 degree wind angle.
Does anyone know a reason why this may be occurring, any advice would be appreciated.
The 90 degree model is here
The 45 degree model is here
I understand that the run time is not as long, but i noticed the convergence not being similar,
I have also realised that my solution for the force did not reach a steady value, meaning the model has not converged
