I am a new user and I am currently using OGS5.7 (downloaded at this link OpenGeoSys-5) I’m actually following the tutorial of the book: OpenGeoSys Tutorial Computational Hydrology II: Groundwater Quality Modeling.
When I execute the code, I have encountered the following problem:
ExecuteKineticReactions Error: odeint not implemented! Warning in CKinReactData::Biodegradation: Odeint did not converge at node 0. -Trying increased relative error 1e-05 Error: odeint not implemented! -Trying perturbation of initial time step usedt Error: odeint not implemented! -Trying conversion of C vector from double to float. Error: odeint not implemented! -Trying perturbation of concentration vector by 1 per mil Error: odeint not implemented! -Trying increased relative error 0.0001 Error: odeint not implemented! ODE integration finally failed. Skipping this node.
I have also tried to execute the tutorial 1d_xylene_degradation available on-line but i encounter the same error.
Does anyone know what does it means and how to fix this problem?
Thank you in advance,
