I am trying to help a friend with her thesis on Counterparty Credit Risk where she intends to have a somewhat lengthy treatment on Credit Valuation Adjustment (CVA). Specifically I am looking to help her in including some computer simulated experiments which would hopefully illustrate CVA calculations under simulated scenarios.

I have been reading a bit on CVA and have got somewhat fair idea of what's going on. However, I am at a loss to find a document where the "Math" has been distilled and computational aspects highlighted, preferably from a programmer's point of view. I have come across a document, which is part of MATLAB's financial toolbox and it does give me some ideas.

I am looking for suggestions/pointers regarding the same.

PS: I am not averse to understanding the Math, just quite perplexed about the "only Math" aspect.

There are good examples and spreadsheet solutions in John Gregory (2015). The maths is not complex. Computational aspects are step increments in time and simulation. Math will indicate computation ... ! A matter that requires more imagination is computational simulation on a portfolio basis (see Credit Valuation Adjustments -- computation issues).

The hard part of the CVA computation stems from the default probabilities. There is a lot of literature on how to model credit events, but what was being used at global banks was in the ballpark of what was implemented by Duffie
