[TRNSYS-users] Problems using several types in a project

Dear TRNSys users,

 

We developed a new TYPE to simulated PCMs behaviour coupled with TYPE 56.
Unfortunately, there are problems when more than 1 PCM TYPE is introduced
into the project. The TYPE is dynamically design (number of nodes within the
PCM layer, number of layer on both side of the PCMs layer the STORAGE
vector, etc.), the parameter, as well as the inputs are read at each time
step (the IUNIT is forced at each type read: IUNIT=INFO(1)) and as well as
the STORAGE vector.

 

No problems are identified using only one TYPE in a project but when more
than one TYPE is used (we just copy and paste the first type and we change
an input), the PCMs TYPES inputs seem to be mixed. The time step used has
also an influence on the results.

 

We might think that the state of the nodes at each time step from several
PCMs TYPES is mixed from one unit to another (e.g. within the STORAGE
vector). But we think we have followed the documentation on the use of
several TYPEs within the same project.

 

Does any one have an idea?
