Unmatched dimensions in Buildings.Fluid.Storage.StratifiedEnhancedInternalHex

[rubenbaetens]

When using Buildings.Fluid.Storage.StratifiedEnhancedInternalHex i constantly get errors for the connection of the internal hex to the tank. e.g.

  Buildings.Fluid.Storage.StratifiedEnhancedInternalHex tan(hTan=1.2, hHex_a=0.1, hHex_b=0.3, nSeg=12, hexSegMult=2)

gives

Unmatched dimension in connect(tan.indTanHex.port[5], tan.heaPorVol[13]);
Unmatched dimension in connect(tan.indTanHex.port[6], tan.heaPorVol[13]);

but at first sight i can't figure out the error.

Note, the error only occurs when nSegHexTan > 1.

@rubenbaetens
The problem occurs because the loop that connects the heat exchanger and the fluid volumes in incremented in the wrong direction if hHex_a < hHex_b.
I will correct it for the next release.
