Yes. It is possible. You have to mesh in the gmsh script. I would say have denser<span> </span><u>Transfinite</u><span> </span>mesh along the formation of boundary layer.</div>

This is a nice visualization on how transfinite mesh can be formed and distributed from denser to coarser and vice versa by altering the<u><span> </span>Progression</u><span> </span>parameter in the script. </div>

<div dir="ltr">Dear Gmsh developers,
<div><br>
</div>
<div>We would like to generate a high-quality mesh for the Fluid-structure-interaction simulation.</div>
<div>The Geometry is read from a CAD file (step). The inner block in the red circle is the solid domain and the outer block is the fluid domain. </div>
<div>We hope to refine the mesh only on the fluid-solid interface while remaining the coarse meshes in the rest of the domains. Is it possible to do that?</div>
<div>The geo file is attached.</div>
