Some changes you may have noticed

Our Windows simulations are currently signed with a certificate belonging to SIAM Limited. That will expire soon, and I am waiting for a new personal one to be approved.

Discussion group

We now have a discussion page on this web site, labelled Blog. Only your first post there will have to be moderated,.

We still have a group on Groups.IO, at:
https://groups.io/g/SIAMulations/.

Replacement for 4 for 3 offer

Our new software can’t handle our old 4 for the price of 3 offer.

Instead, use coupon code IC125 on checkout to get £25 discount when you spend over £100, i.e. £101 or more.
