Fastran

[Gust]

Just curious, ACE seems to be CFDRC's primary focus but we only use the Fastran solver from CFDRC. Sometimes we wonder how many others use Fastran.

I use it as well. Infact it's our primary cfd-tool.

CFD-ACE+ is widely marketed to multiple industries, but CFD-FASTRAN is marketed primarily to aerospace. This is why you hear more about ACE+ than FASTRAN. CFD-FASTRAN is very good for its applications and has a good reputation among the customers, but there are more ACE+ customers.

I wonder if there is somebody who know exactly how to define Reynold's number in FASTRAN, expecially the characteristic value "L" in the equation (Re=L*v/n). I will be glad for all information on my e-mail: [e-mail]
thanks

Hi,everybody.
I find there are so few people in this forum.Why?
I'm a beginner of CFD,and I have many questions to ask.When i have logged on, I felt little depressed.But I expect to get some good echos from here.Thank you very much.

Could I ask some questions about CFD-Fastran and CFD-View?
1, How can i estimate the value of k and e in CFD-Fastran solver?
2, How can i plot the vorticity magnitude in CFD-View?

[Pikachoo]

k = 0.5*(0.01*U)^2....where U is the freestream velocity

e = 0.09*rho*k*k/4/mu

where: rho is the density (kg/m3)
k is determined from above
mu is viscosity

[w0er]

Thank you.but when i check k and e on wall in CFD-VIEW .I find they are much bigger than the value given by these functions.

what the hell my account is still pending ?
are you there? lazy guy.
