Update the RM3 model lower and upper bounds

[a1708192]

Dear Authors,

Thank you so much for developing this open-source professional WEC simulator and publish it.

Could you please suggest how we can set a wider range for lower and upper bounds of the RM3 model?
I am just worried about the mechanical constraints of the RM3 model to provide a feasible model by using this new range.
lb = [r1=4.5, r2= 7, d1=1.00, d2= 41];
ub = [r1=5.5, r2=8, d1=1.25, d2=43];
What can be the feasible minimum size of r1, r2, d1 and d2? and the same question is that What can be the feasible maximum size of r1, r2, d1 and d2?

Thanks a lot in advance,

Hi @a1708192 - Thanks for your interest in WecOptTool

These dimensions can really be whatever you like, depending on your specific interests. Perhaps you can elaborate a bit more on your question? What do you mean by "the feasible minimum size?" Are you asking, e.g., about what is valid in terms of the modeling assumptions or what is practical in terms of the economics of the system?

Thank you for your response. I think we can talk about the variables in terms of the modelling assumptions.
For instance, if we set r1 and r2 by 1 (minimum size) and 10 (maximum size) are correct initialisation. What is your idea about d1 and d2?

I don't see any problems when setting these types of values. In general, the only thing that you may need to watch out for is the quality of the surface mesh use for Nemoh. If you are getting solutions that seem questionable, this would be a good first thing to check. Otherwise I really think you can use whatever bounds you like. The same goes for all of these design variables.
