Mk error
I don't understand why this error is reported. And where is the ".../DSPH-Chrono-Lib/Source/JChronoData.cpp" file

Play around with "bodyfixed" and "bodyfloating" in Chrono, you have probably used the wrong term or made a mistake in making something a fixed or floating body.
Kind regards
Yes, indeed mistake happen when I create a floating body. I have created a floating in Case.xml, and the chrono_objs folder have this floating, but when i add "-debug:10" to the gencase, I have found no floating appear. I'm very confused.
My model have a floating object which subject to free motion, and also have a floating with an artificially given movement, I want to know whether the mk value has an order, and whether it can be freely given within a certain range
Mkbound values should be able to go up to ~2000. Mkfluid goes from 0 to 9 per default.
Perhaps your floating object has not been drawn / no particles produced. So there is nothing for chrono to grab on.
My advice would be to redo the case from scratch so you step per step can figure out the error.
Kind regards
Yes, it's no particles produced that cause this problem. And I have found where is the problem( the blue rectangle), but I confused why this problem happened!
What is your dp value?
My dp=0.001m
How do you apply motion to your floating object?
Floating objects right now cannot have motion data applied in the motion category.
You can only do motion on floating objects through linearvel and angularvel - you are sure you are using these right?
Kind regards
I think you don't fully understand what I mean. There are two types of floating bodies in my model. One type of floating body is my research object (it is free movement instead of artificially imposed movement), and the other type of floating body is according to what you said. Give him a linear velocity or angular velocity, this is not a research object, just an auxiliary role. Besides, I want to thank you very much, it is your reply that let me find my mistake, I think my mistake is that I did not consider the dp gap between different model block when modeling, which caused the model to have crossover , so there is no way to generate a floating body object
No worries, glad you fixed the mistake
Kind regards
