Hi all,


 


I want to do an acoustic analysis of a bus cabin with OptiStruct.The bus is exposed to wind effect during driving conditions.To simulate this effect,i used Virtual Wind Tunnel.I could export the pressure values with related  node coordinates.I can use these pressure loads,but these values are in time domain and i need to convert it to frequency domain to use in acoustic analysis. (with FFT etc...)


Is there any way to make this conversion with HyperWorks softwares ?
