j'ai une helice avec un mouvement de rotation de ... rad/s et je veux modeller ca sans utiliser le maillage dinamique. j'ai une idee de donner le mouvement au fluide et l'helise restant fixe mais comme je peut donner ca en fluent et si c'est bien comme ca.

merci

i have a propeller with a rotational speed ... rad/s and i want to modelate this without using dinamic mesh. i have an ideea about doing this but i don't knew if it's working. by giving the mouvement to fluid and the propeller resting fixe. the problem is how to do this and if it a good ideea regarding the results.

thank you

you're saying that i have to give to the fluid the option multiple reference frame with the rotation of .... round an axis and living the propeller fixes or giving the propeler the property of mouving wall with the condition of speed 0 rot/sec
