lumped parameter udf-include pressure profile
 

Dear all,

I want to use a lumped paramter outflow boundary condition for my coronary artery geometry and need to additionaly implement the pressure of the left ventricle there. I am working at writing a udf for this problem and thought of including a profile of this form (one of the normal profiles you can read with "File->Read->profiles"):
((pressure transient 10 1)
(time ....)
(pressure ....))
Is it possible to include it in a normal udf and how can I do this?
Thanks a million for any help and idea!

lumped parameter udf-udf function in certain range
 

I just wanted to add something:
Maybe I could also implement another udf inside the lumped parameter udf describing the pressure profile instead of using a "point profile".
But my problem is: my profile should be periodic, that means it should start at 0s and it's duration should 1s and afterwards it should just start again from the beginning (This should go like this for about 50 times). Since it is a fit function, only the values of the function in a certain range (0-1s) are interesting for me. Is there a way to define this?
Thanks a million for any help and ideas!
