I fear you have to be a little bit more precise in what you are really intersted in. What physical properties are you looking at? What are the geometrical parameters of the model you would like to work with?
i guess you want to simulate the process of coating growth during either of the one coating deposition process. In this case CFD software such as FLUENT is readily useful.

I`m looking for compatibility of one polymer to a surface, and investigation of properties on this modified surface by modeling.(for example)
Do you know any software for this target?
Thanks.
You can find a lot of them on web. Let me know if you find it difficult to get access to them
I am so sorry for disturbing you. Please send for me the topics of some articles.
Thank you.
I would recommend you Comsol Multiphysics, which is quite similar to ANSYS Fluent and is very useful if you are not willing to learn simulation from the scratch. You should be able to handle it pretty fast!
You are interested in possible chemical reactions between the polymer and the substrate or you would like to calculate the interaction force? In the end you would like to know how the coating influences the mechanical properties of your substrate?

Sorry for the delay. Unfortunately Comsol is not made for predicting chemical reactions but you can definitely simulate the mechanical property change due to the coating with the structural mechanics module.
If you are interested in the related field of the coating process we are performing hydrodynamical simulations with Fluent regarding the droplet transport from the atomizer to the target and the dynamics of the droplet impact. If you like we can exchange about these topics.
Hi Dr.Oliver Tiedje
I`m interesting in that field, but I don't enough to dominate over fluent.In spite of all that l like to exchange about theses topic with you.
Best regard.
To know the coating influence ypu have to take the interactions between coating and substrate relying on few experiments. Then you can optimise that using DOE (Design expert 8) where it will tell you precisely with high confidence the influence of the coat.
I meant Design expert8 can do the job and it is cheaper if you want to update to higher version is Ok. Thanks anyway
Dear Seyed Razavi,
FLOW-3D CFD can be used.
Optimizing coating processes can be difficult to model due to small scale of fluid motion and the influence of effects such as wall adhesion and surface tension. This provides a convenient way to analyze these processes without having to resort to costly laboratory experiments. FLOW-3D‘s models can simulate surface tension gradients due to temperature variations, heat transfer, vaporization, condensation, solute transport and density-driven flows.
This FLOW-3D simulation of a forward roll coating process captures a ribbing defect due to a high capillary number. The model incorporates the effects of surface tension and viscosity as the backing rollers draw the fluid through a 400 micron nip. The accurate prediction of the onset of ribbing allows for researchers to identify optimal process parameters to avoid defects.
Hope this is helpful for you.
