I already try to solve this error but still cannot solve it. Anyone can help to solve this error. Error: Failed to find consistent initial values.
Division by zero.
Function: /
Failed to evaluate variable.
Variable: comp1.plas1.jz wCH4, Defined as: (comp1.plas1.rho*comp1.plas1.Dm wCH4)*((-d(comp1.plas1.wCH4,z))-((comp1.plas1.wCH4*d(comp1.plas1.Mn,z))/comp1.plas1.Mn))
Failed to evaluate expression.
Expression: dvol spatial*(r*(pi*((-2)*(-comp1.plas1.jz wCH4))))
Failed to evaluate Jacobian of expression.
Expression: (-2*(comp1.plas1.rho*comp1.plas1.wCH4*d(comp1.WCH4,t)*test(comp1.WCH4)-comp1.plas1.jr wCH4*test(d(comp1.WCH4,r))-comp1.plas1.jz wCH4*test(d(comp1.WCH4,z))-comp1.plas1.R wCH4*comp1.plas1.M wCH4*test(comp1.WCH4)+comp1.plas1.rho*comp1.plas1.wCH4*(comp1.plas1.ur*d(comp1.WCH4,r)+comp1.plas1.uz*d(comp1.WCH4,z))*test(comp1.WCH4))*pi*r)*(dvol spatial)
Last time step is not converged.
