[TRNSYS-users] Parallel Simulation with Type155

["Hermann Schranzhofer" <hermann.schranzhofer@tugraz.at>]

Dear TRNSYS User,

 

we found out that it is not possible to start more than one simulation in parallel (using e.g. a multicore processor) if there is a Type155 (MatLab connection) used in the simulation. It seems that the MatLab Workspace is using the same Memoryspace and so the simulation breaks down if a second one is started.

Is someone out there who can help me with this problem?

 

Best regards,

Hermann Schranzhofer.

Betreff: Re: [TRNSYS-users] Error 50

Dear Ramkishore,
 Increasing the number of surfaces that Type15 calculates adds a lot of parameters to your simulation. So many, in this case that your simulation exceeds the total number of parameters allowed per simulation. In addition to your change in Type15.f90, you also need to change TrnsysConstants.f90 as follows:

Integer, Parameter :: nMaxParameters      =     4000  ! Maximum number of Parameters                                2000

in other words, increase the total number of allowed parameters, then recompile the TRNDll.dll.
Kind regards,
 David

Dear All,

I am using type 15-6 and type 56 components for simulating a spherical building that is defined by 144 surfaces. I have connected successfully all requiered connection between two. One error 50 arrive at the time of running the model. Though, I have changed the ns_max=200 from 25 in Type 15.f90 [Parameter (ns_max=25,nitems_max=36,nout=52+8*ns_max)] file. The screen shot is attached herewith for your kind reference.

 

I would be very thankful if anybody can help to resolve this problem.
