Illegal Characters

When you enter certain names for objects or projects, some characters are automatically replaced with an underscore (“_”). This is due to the parametric computation logic used internally. These characters can interfere with parametric equations and cause unexpected results.

For example, if you name an object PierCap1+5, OpenBrIM interprets this as a parameter named PierCap1 plus the value 5, rather than a single name. To avoid such conflicts, the following characters are not allowed:

Illegal characters:

• (space)
• ' (single quote)
• \ (backslash)
• / (forward slash)
• | (vertical bar / pipe)
• ? (question mark)
• * (asterisk)
• - (hyphen)
• + (plus sign)
• < (less than)
• > (greater than)
• : (colon)
• . (period / dot)
• @ (at sign)
• & (ampersand)
• ( (left parenthesis)
• ) (right parenthesis)
• % (percent sign)

All of these will be replaced automatically with an underscore (_) to ensure parametric stability.
