Hi, im using a UDF to gradually rise the pressure of a bc from a start value to an end value. Start and End value are parameters in Workbench.
In oder to get them into the UDF i go to input parameters - use in scheme - and set the following command for both the start and the end parameter (of workbench): (lambda (param) (rpsetvar 'pstart param))

This works fine when i set it up and then press update - but when i change the design point (upstream mesh changes, pstart and pend stays the same) it does not work anymore (looks like the values dont get passed into the udf anymore resulting in the pressure being zero). (Solution monitoring also tells me it could not find pstart and pend (so the variables the udf tried RP_Get_Real) - i just dont have a clue why it doesnt find them anymore when it worked in the previous run before i switched design points

Anyone having an idea what i did wrong or a tip what to look out for when using UDFs with WOrkbench parameters?
