Hi, Andreas,
In my simulation on cyclotron cavity multipacting, I just treat the direction of the height of the cavity as Z, and X axis is the symmetrical line of the cavity along angular direction. I don't know how does Jianjun model the cyclotron cavity in OPAL-cycl.
But as far as you know the way how OPAL-cycl treat the cavity field map, you can just modify the converter to read the ASCII field map and convert it into the right XYZ which fit the OPAL-cycl. 
I have to find the converter somewhere in my laptop and I'll send it to you when I come back to home.
Best regards

Ok great! 

However there is one thing, because in OPAL-t the y and z axis are  different than in OPAL-cycl where did 
you take that into account?  

In the converter frpm ANSIS to H5Block?

Hi, Andreas,
I have not implemented the BoundaryGeometry stuff in OPAL-cycl.

However, various 3D cavity field maps are ready for simulation, which are mainly based on the H5Block lib. The one I used to simulate the multipacting in cyclotron is the FM3DH5Block_nonescale.cpp. Which basically use the order that data varies fastest in X and slowest in Z. And this field map does not scale using scale factor defined in RFCavity class.

I'll find the example of ASCII file and the converter I made using H5Block lib and send them to you if you need them.

Best regards
