At the top of my google search:

“Alimony in solido consists of a definite sum of money that is paid in a lump sum or in installments over a definite period of time.”). “A typical purpose of such an award would be to adjust the distribution of the parties' marital property.”

Sounds like a property settlement.  "Here's your half of the house, but rather than sell the house, I'll get a second job and pay your $250,000 share in ten annual installments of $25,000 each."
