Dear @Matthew.Hall ,
Sorry for being so demanding ! (I just wanna understand what is done behind MoorDyn dll).
I was reading MoorDyn User’s Guide - December15, 2015. So, if i understand well:
-
dtC is the coupling time step. Is it user defined ? In fact, it is written in page 4 that MoorDyn adjusts its internal time step size dtM. For me, dtM is specified in the input file in solver options. Could you please clarify this point ?
-
I will say that dtC is user defined. Therefore, it is an input argument for the function LinesCalc (MoorDyn in C++). If i fix dtC to 0.01 sec and dtM is defined in the input file and it equals 0.001 sec, that means MoorDyn will do calculation for N =dtC/dtM=10 steps ?? Could i choose these two parameters such that N=1 in order to let MoorDyn computes fast ?
-
Finally, in order to be sure that i get it: In the page 13 in the same document, you provide an example how to couple MoorDyn with MATLAB. In this example the variable dt is dtC right ?
Best Regards
