Use Views Bulk Operations http://drupal.org/project/views_bulk_operations. I would think you just need to do something that generates a node save so you could do something as simple as publishing all nodes (if applicable) and then you would get your results.

Hope this helps.

Subject: [support] Computed fields module(Auto calculation for existing node fields)

Hellos,

I am using the computed fields module to do some calculations  for some node fields. It is working fine

The issue is that the fields being computed came before,  I installed the computed filed module.  What is happening is I ahve to edit and save the node for the computtions to take place.  I there a work around since the nodes are too many, for me to edit one by one.

Thanks
