Strain energy function for Mooney Revlin model ( from Literature)

W= c1*(I1-3)+C2(I2-3)+D1[exp(D2(I1-3))-1]

C1, C2 , D1 and D2 are material constant. Unit for all the terms are Pa

But in CFX , I could not find c1, c2, D1, D2 instead I found c10, c01, c11 and it is treated as material constant with unit Pa
but i found only one D the unit for D is Pa^-1

any one help me or explain about this

Thanks
