simulation metal particles and gas flow in cfx
 

hi! now i have a preoblem. i want to run a simulation. the mixture of metal particles and argon gas is sprayed in the air. the gravity is not neglected. i want to simulate it by cfx. can i? should i use user fortan or cfd code? has any any bode an idea?

Yes, CFX can do this.

hi dear! thanks for your answering. do i need any cfd code and user fortran in cfx? i want to simulate the laser cladding process from begining of the nozzles untill melting of metal particles by laser. and i want to choose the best software. fluent or cfx? excuse me.

The question is vague and very broad and I have no idea what the important physics is. I generally do not bother answering questions which cannot be answered without lots of extra digging ...... and it looks like Erik feels the same. See http://www.cfd-online.com/Wiki/Ansys...ible_answer.3F
