|TSOL|Solidus temperature|
|TLIQ|Liquidus temperature|
|VITCOUL|Casting speed|
|GAMMA| Specific weight|
|ZINI|Initial depth under meniscus|
===== Stresses =====
==== Number of stresses ====
1
==== Meaning ====
|T < TSOL|PRESS = 0|
|T > TLIQ|PRESS = GAMMA * (VITCOUL * TIME + ZINI)|
|TSOL < T < TLIQ| PRESS = GAMMA * (VITCOUL * TIME + ZINI) * (T-TSOL) / (TLIQ-TSOL)|
