Hi Sri When working with ASCEND, it has been my experience that it's very important to build up your model from small, well-tested sub-components. For example, from your model I can see that you have some sun-position calculations (I implemented something similar in ASCEND, see models/johnpye/sunpos.a4c), as well as some heat transfer correlations.
It's not quite clear to me yet what it is that you want to model though -- is it a linear concentrator of some sort? If so, I suggest you create an array of finite elements, and allow the ASCEND solver to work out how to solver all of the elements, rather than writing your own loops. There is an example of the advection equation to show how 1-D finite-difference models can be constructed in ASCEND. http://ascendwiki.cheme.cmu.edu/FOR http://ascendwiki.cheme.cmu.edu/Worked_examples#Simple_advection_equation Try to change your model so that it's a 'model of models', built up out of simpler sub-models. The syntax for this is summarised here: http://ascendwiki.cheme.cmu.edu/Object-oriented_modelling I hope that this helps a little. If you describe what you are trying to do in a little more detail, I might be able to give some more assistance.
