Previous Solution as Constant

Hey all,
I have a question regarding a multiple study setup. I would like to use the last value of a variable defined in one study as a constant in a variable for the next study. So for example:
My first study - study 1 - heats up the model for a certain time which gives me a temperature T(end). Now I want to use this T(end) to define a variable in the second - study 2 - which uses this expression T(end) like: Tref = T(end)+t*10[deg]
How would I go about doing this?
thanks in advance for your help

Hi,
You can use the 'withsol' operator to point at results from a previous solution. There are several different possible sets of arguments to this operator, depending on the level of detail you need for picking the right set of results. You can find the details in the documentation.
In the simplest case you would write an expression like
withsol('sol1',T)+t*10[deg]
A call like
withsol('sol1',T,setval(t,0.5))
will pick the temperature from t=0.5 in solution sol1, etc.

Henrik
