unknown unhandled exception error

Hello dear,

The software gives error message "Unknown unhandled exception; terminating the thread in which it happened". I have entered user defined data but due to this error, I am unable to simulate the results. Please help me to fix it. Thank you.

Annual Energy Production

I am conducting a simulation of parabolic trough CSP plant using SAM. One of the configurations is using solar field with fossil boiler backup without thermal storage. In this case, the calculated annual energy production and net capital cost are in negative (-) sign ?! what is that mean?

Thermal storage dispatch control in IHP trough model

I am trying to model IPH using PTC system and auxiliary boiler powered by natural gas. I would appreciate someone to help to answer the following question
How to implement Thermal storage dispatch control in IHP model in SAM?

Field HTF energy inertial

Hello

I calculated the solar fiel warmup energy using the method descried in (sam_trough_model_type805.cpp) for empirical model but when i compare it with the calcul of Field HTF energy inertial (consumed), i don't have the same result.

how can i calculate the Field HTF energy inertial (consumed)?

I don't have the same calcul of everage temperature and Field HTF energy inertial (consumed).
the calcul warmup energy is the same of Field HTF energy inertial (consumed)???????

Yours sincerely

Internal Energy

Hello;

In my understanding : (Field Thermal Power Produced = Field Thermal Power Absorbed – Field Thermal Power Header Pipe Losses - Internal Energy Increase). How to calculate the Internal Energy Increase for parabolic trough plant??

Thanks in advance
Best Regards

parabolic trough

Hello

I would like to know how SAM calculates:

Field thermal power absorbed
Field thermal power dumped
Field thermal power receiver loss
Field thermal power header pipe losses
Field thermal power produced

and the relation between them. (version 2017.9.5)

best regard

How to apply changes to the source code?

Dear all,

I'm trying to derive the condenser pressure (P_cond) from the CSP parabolic trough physical model. Since this variable was not one of the defaulted outputs, I guessed I needed to modify the source code a little bit. But I found that I couldn't apply any change even after I modified the code. Here's what I did to test for the modification:
