non-uniform oscillatingDisplacement
 
Hi all,

does anybody know how to impose a non-uniform deformation to an oscillating plate?

i've been trying to use the oscillatingDisplacement boundary condition but it seems not to support a non-uniform displacement of the patch points.

Thanks in advance!

Hey guys! check this out http://www.tfd.chalmers.se/~hani/kurser/OS_CFD_2008/

I found what i needed in Eysteinn Helgason's work.

keep up the good work guys!

Dear Gricci:

I also need to conduct the same kind work as you. Have you solved this problem? Would u please give me some hints on it?

Thanks and best regards!

Hi folks,
thank you for your interest in my work, but unfortunately I'm not working in the field of CFD from way back and I cannot help you. However I do remember that the link above has much of the information I needed!
Good luck

Dear Gricci:

Thanks for your reply. As you suggested, I have referenced Eysteinn Helgason's work of
Point-wise deformation of mesh patches. But, it is pity, I didn't understand it totally. How does make the deformation amtiputde changing with time?

From the function of for instance, Z= Ax**2+By**2. It can not find time, but I find the deformation changes in one period. Another question is whether x, y is same location as the initial location in the patch.

Thanks for so much!

Best wishes!
