[@blackguardian89]

Thanks again, Josh! Looking forward to your next videos about VPM :)

[@JoshTheEngineer]

No problem! Trying to film them this weekend.

[@Dani-ox6yw]

Love your videos. Your hard work is really appreciated bro. Thanks alot :)

[@JoshTheEngineer]

That's really nice of you, thanks!

You are the best Josh! Fsr, I'm getting errors in line 81, and line 103 and idk how to fix it.

[@JoshTheEngineer]

Thanks! I would need you to post the exact error message you're getting, otherwise I'm not sure I can help.

[@SangJin-Nick]

thank you :) I have a question, how to change the length of cord ?

[@carlosmaldonado8600]

Thanks mate!

You're welcome!

hi josh, why didn't you calculate the source strength in this video?

[@JoshTheEngineer]

I'm not sure what you mean. At 1:21, you can see the code block where I calculate the source strengths, and at 7:03 I go through that code block. The source strengths are calculated on line 173.

Bug report: Run "clarkysm.dat", error occurs because of atan2 when solving the second term in Mx equation.

Changing the default 170 panel nodes is able to skip this "bug" of finite discretization.

[@JoshTheEngineer]

Thanks for pointing this out! I updated the STREAMLINE_SPM.m file to set E to zero when it is imaginary or a NaN. This way you don't need to change the number of panel nodes.

@@JoshTheEngineer Thank you! By the way, when will be the next video ready for updating? Looking forward to it. Again, many thanks.
