Reviewer's Guide

Refactored the gRPC connection setup by extracting the multi_connect logic into a private helper and exposing a new public reconnect_to_mapdl API that can re-establish dropped connections with an optional timeout, replacing the inline connection code in the constructor.

Hey @germa89 - I've reviewed your changes - here's some feedback:

• Replace if not timeout: with an explicit if timeout is None: check so that a zero timeout can be handled correctly.
• Add explicit -> None return type annotations to both _connect_to_mapdl and reconnect_to_mapdl for consistency with the existing type hints.
• Consider returning a status flag or raising a custom exception in reconnect_to_mapdl to clearly signal success or failure to callers instead of implicit None.

Here's what I looked at during the review

• 🟡 General issues: 1 issue found
• 🟢 Testing: all looks good
• 🟢 Documentation: all looks good

suggestion (bug_risk): Use timeout is None instead of falsy check

This prevents valid falsy values (e.g., 0) from being overridden by self._timeout.

Suggested change

	if not timeout:
	timeout = self._timeout
	if timeout is None:
	timeout = self._timeout
