Default Finding max value using Field Functions

Hello all,

I am currently trying to refine my mesh using AMR, and I am using field functions as criteria. One of my field functions is dependent on cell length, where cell length is the largest dimension of the cell.

For instance, I have three variables, ${CellLengthAxi}, ${CellLength2D}, & ${CellLength3D}. I want to save my variable ${CellLength} as the max of the three length variables listed above. I tried writing a whole boolean statement, but it isn't working, unfortunately.

Is there a way to save those three length variables in an array, and just call a max function to obtain the max and save that value as ${CellLength} . If there is an easy way to do this, let me know! Thanks in advance!!

There are many ways to achieve this, for example you can nest two max functions: max(max(${CellLengthAxi}, ${CellLength2D}),${CellLength3D})
