This seems like a User-defined result. Can you please elaborate on what these variables, ENVM, UA, and SOLN are? and why these variables are used?

Dear Saumadeep It is user-defined result. I have not used these expressions, kindly explain what this expressions denotes. What is UA and SOLN?

As you mentioned this is a user-defined result. So, once a user-defined result is imported, it's mandatory to input the expression, so the expression that you see in your result has been imported by the user.
The expression can be defined as one of the predefined "available solution quantities" (which can be accessed in the Worksheet, please refer to the steps shown in the image below to see how to access the Worksheet). Check all the expressions given in the list as given in the worksheet.

Another way to define the expressions for user-defined results is by using identifiers of previously defined results. (as shown in the image below, where Equivalent Stress is defined by identifier - "a" and Middle Principle Stress is defined by identifier - "b", and both the final user-defined result is defined by expression - "a + b")

Since the terms you mentioned (ENVM, UA, and SOLN) are not in the worksheet, I think they are defined as identifiers for other results and then used in the expression for the user-defined results, as shown above. Please check if that is the case.
