What is tpos
I am working on the example 7.1 fluid flow in mixer. While I have to write a file named cgrid.cgrd

but it's really bordering me and i can't find any hint about the content, for example:

*SET TANG TIME * DPS ! to calculate the tan value

*GET TPOS Y 37 !in this sentence,what does "tpos" mean?

*SET TOFF TANG - TPOS !and what does this whole sentence mean?

Thank you guys a lot!

Star-CD is really hard for me to study...Jesus!

Re: What is tpos
TPOS is a user defined variable which is the angular position of vertex # 37.

*SET TOFF TANG - TPOS means that the user defined variable is given by the difference between the variables TANG and TPOS.

Hope this helps...

Re: What is tpos
I think that would help... Refer to the tutorial(s) and the user guide.

"*GET TPOS Y 37"

what does the "Y" mean?

I could suggest trying help *get to find out.

However, to be helpful, it is the second direction of the currently define co-ordinate system (the one set by CSYS - system 1 the global cartesian by default).

In this case the person is calculating the desired position of the crank, measuring the current position and then creating an offset of the difference.
