How to find the total mass modeled in the Mass Reference Load case?

Whenever a dynamic analysis of the model is performed, a file ending with _MASS.TXT is created in the same folder where the model is saved. If you open this file with any text editor (i.e. NotePad), you will find a list of masses for each node in each global direction. The last line in this file is the sum of masses of each node in that direction.

Note: the data in the MASS.TXT file is always in English units (lb in) irrespective of modeling units. You will need to make a unit conversion manually.
