How can i use measure tool to measure the value on a moving floating

JOJOJOJO
in DualSPHysics v4.4

hi, forum.

I want to measure the pressure on a point attached on a floating object. And the trajectory of this floating is unpredictable.

I read the help file of MeasureTool and i don't find the way to set a point attached on floating object. But there is a potential alternative, using the id of particles. So, i modifidy like this:

%MeasureTool% -dirin %dirout% -particlesid:2529 -vars:+press -onlytype:-all,+fluid %dirout2%/PointsPressure -savecsv %dirout2%/_PointsPressure

id=2529 is a particle of floating on the edge. But i get a error information:

Text: Variable 'id' is not defined in list of valid variables [Idp,3:Pos,3:Vel,Rhop,idps,Press,Press,Mass,Vol,Type,Mk,3:Ace,3:Vor].

How can i fix it, and, is there any other way to measure the values on a arbitary point?

    Hi JOJO,

    The option -particlesid did not work, so you can find a new version of MeasureTool in the branch develop of GitHub repository (https://github.com/DualSPHysics/DualSPHysics/tree/develop).

    Other option is to use BoundaryVTK to create a CSV file with the position to use in MeasureTool. This program create this CSV file by applying the movemento of an object (mk) to an initial position. This technique is used in the example main\05SloshingTank\CaseSloshingMotionDef.xml to measure close to boundary of a moving tank.

    Best regards
