If it is a finite-element mesh (e.g. a tetrahedral or quadrilateral mesh), then you could in principle use [Gridap to interpolate](https://gridap.github.io/Gridap.jl/stable/Fields/#Gridap.Fields.Field) using finite-element basis functions (e.g. first-order Lagrange elements to interpolate linearly from nodal values).
