topic Iterating a solve block, plotting results on graph in Mathcad https://community.ptc.com/t5/Mathcad/Iterating-a-solve-block-plotting-results-on-graph/m-p/91632#M36264 <HTML><HEAD></HEAD><BODY><P>Hi again. </P><P></P><P>Continuing to work on my sheet that estimates the top speed of an aircraft in level flight. I would like to plot level speed against altitude, similar to this curve here for the real WW2-era P-51D fighter I am using to validate my model: <A class="active_link" href="http://www.wwiiaircraftperformance.org/mustang/P-51D_15342_Level.jpg" target="_blank">http://www.wwiiaircraftperformance.org/mustang/P-51D_15342_Level.jpg</A></P><P></P><P>For whatever reason (and I feel like a moron) I find the documentation for mathcad to be unclear. It's like it's skipping some fundamental step that I haven't learned yet. Same goes for most of the tutorials I find.</P><P></P><P>In any case, here is my question at the moment:</P><P></P><P><STRONG>Should I iterate my solve block a few times, and then use a curve-fitting algorithm to get a nice graph? Is there an easier way to get a curve?</STRONG></P><P></P><P>I'm not even sure if I'm approaching this the right way. I tried to follow this tutorial: <A href="http://www.imakenews.com/ptcexpress/e_article001008454.cfm?x=b11,0,w" target="_blank">http://www.imakenews.com/ptcexpress/e_article001008454.cfm?x=b11,0,w</A> as an example but I keep getting tripped up. I could define altitude, horsepower, and weight as vectors below the solve block like the tutorial does, but some of the parameters above the block require these values as inputs.</P><P></P><P>Then I thought maybe I could use a "program" but I read that you can't put a Given statement into a program.</P><P></P><P>If anyone could shed some light on this, I'd appreciate.</P></BODY></HTML> Thu, 03 May 2018 18:29:21 GMT ptc-4390973 2018-05-03T18:29:21Z Iterating a solve block, plotting results on graph https://community.ptc.com/t5/Mathcad/Iterating-a-solve-block-plotting-results-on-graph/m-p/91632#M36264 Hi again.
