As I understand you have a special method for filling domain from request. At this case you could pass all params (it's a Map) to such method, like:

def MyDomain {

  static MyDomain buildFromParams(def params) {
     return new MyDomain(
         field1: params.field_1, //assuming that your params have different naming scheme so you can't use standard way suggested by Raphael
         field2: params.field_2
     )
  }

}

class MyController {

  def myAction() {
     MyDomain foo = MyDomain.buildFromParams(params)
  }

}

IF your parameter names are propertly formated and match the domain attributes, you can do this:

Assuming 

params = [name:"some name", age: "194", civilState: "MARRIED"]

and

class Person{
   String name
   Integer age
   CivilStatus civilState //some enum
}

You can leverage groovy's property binding constructor like this in a controller:

class Controller {
   def saveAction = {
       new Person(params)
   }
}

If by "Model" you mean a Domain Model class, they don't have params, they're just POJOs. Params only apply to Controllers, as far as I know.
