Default pressure gradient???
Posts: n/a
Hi Hey everyone. How to define pressure gradient in fluent. I know there is a macro C_P_G(c,t) to define pressure gradient. But i need dimentionless pressure gradient. So I need to define it as dp/dx. Where dp is the pressure difference and dx is the distance between adjacent cell centers. Can anybody help me. Thanks in advance. Mech

Hi Mech, You could defined pressure gradient using a macro C_P_G(c,t)[i]: dp/dx as C_P_G(c,t)[0], dp/dy as C_P_G(c,t)[1], dp/dz as C_P_G(c,t)[2].

I hope I help you. Tomik

Hi Tomik What you written is known to me. I already mentioned how to express pressure gradient by using macros.Perhaps you did not understand. Please read my writing carefully. Anyway thank you for your response.
