I am implementing this equation

dT/dt=k1/b(k2x-T(1+k2/k1)+A+bdx/dt)

i am using coefficient form pde every time its showing error time dependent solver..unknown function T..

what i have done is i have made cylindrical geometry ,meshed it ,added elasticity as material property,added pde then computed .i need to calculate Force(T) vs t....elongation(x) vs t..

how to do?

Hi,
You need two equations if you want to calculate the two unknown functions.
